This file can then be assigned or installed to a server and used for SSL/TLS connections. To create a PKCS#12 keystore for these tools, always specify a -destkeypass that is the same as -deststorepass. This option can be used independently of a keystore. It enables users to administer their own public/private key pairs and associated certificates for use in self-authentication (where a user authenticates themselves to other users and services) or data integrity and authentication services, by using digital signatures. In other cases, the CA might return a chain of certificates. Important: Be sure to check a certificate very carefully before importing it as a trusted certificate. This entry is placed in your home directory in a keystore named .keystore . Subsequent keytool commands must use this same alias to refer to the entity. The signer, which in the case of a certificate is also known as the issuer. For example, JKS would be considered the same as jks. Keystores can have different types of entries. The keytool command works on any file-based keystore implementation. Similarly, if the -keystore ks_file option is specified but ks_file doesnt exist, then it is created. Use the -importcert command to import the response from the CA. Where: tomcat is the actual alias of your keystore. You could have the following: In this case, a keystore entry with the alias mykey is created, with a newly generated key pair and a certificate that is valid for 90 days. How do request a SSL cert for reissuing if we lost the private key? Before you consider adding the certificate to your list of trusted certificates, you can execute a -printcert command to view its fingerprints, as follows: View the certificate first with the -printcert command or the -importcert command without the -noprompt option. The X.509 standard defines what information can go into a certificate and describes how to write it down (the data format). Import the Root certificate 3. The following terms are related to certificates: Public Keys: These are numbers associated with a particular entity, and are intended to be known to everyone who needs to have trusted interactions with that entity. If -destkeypass isnt provided, then the destination entry is protected with the source entry password. It generates a public/private key pair for the entity whose distinguished name is myname , mygroup , mycompany , and a two-letter country code of mycountry. Commands for Importing Contents from Another Keystore. Certificates are used to secure transport-layer traffic (node-to-node communication within your cluster) and REST-layer traffic (communication between a client and a node within your cluster). For example, Purchasing. The destination entry is protected with -destkeypass. Manually check the cert using keytool Check the chain using openSSL 1. If you press the Enter key at the prompt, then the key password is set to the same password that is used for the -keystore. The data to be imported must be provided either in binary encoding format or in printable encoding format (also known as Base64 encoding) as defined by the Internet RFC 1421 standard. Brackets surrounding an option signify that the user is prompted for the values when the option isnt specified on the command line. The -sigalg value specifies the algorithm that should be used to sign the certificate. This is because before you add a certificate to the list of trusted certificates in the keystore, the -importcert command prints out the certificate information and prompts you to verify it. Provided there is no ambiguity, the usage argument can be abbreviated with the first few letters (such as dig for digitalSignature) or in camel-case style (such as dS for digitalSignature or cRLS for cRLSign). After you import a certificate that authenticates the public key of the CA that you submitted your certificate signing request to (or there is already such a certificate in the cacerts file), you can import the certificate reply and replace your self-signed certificate with a certificate chain. The other type is multiple-valued, which can be provided multiple times and all values are used. Now, log in to the Cloudways Platform. certificate.p7b is the actual name/path to your certificate file. Otherwise, an error is reported. This sample command imports the certificate (s) in the file jcertfile.cer and stores it in the keystore entry identified by the alias joe. The two most applicable entry types for the keytool command include the following: Key entries: Each entry holds very sensitive cryptographic key information, which is stored in a protected format to prevent unauthorized access. If required the Unlock Entry dialog will be displayed. Since Java 9, though, the default keystore format is PKCS12.The biggest difference between JKS and PKCS12 is that JKS is a format specific to Java, while PKCS12 is a standardized and language-neutral way of storing . Passwords can be specified on the command line in the -storepass and -keypass options. The keytool command supports these named extensions. If you request a signed certificate from a CA, and a certificate authenticating that CA's public key hasn't been added to cacerts, then you must import a certificate from that CA as a trusted certificate. Copy and paste the Entrust chain certificate including the -----BEGIN----- and -----END----- tags into a text editor such as Notepad. Subject public key information: This is the public key of the entity being named with an algorithm identifier that specifies which public key crypto system this key belongs to and any associated key parameters. If you have the private key and the public key, use the following. Make sure that the displayed certificate fingerprints match the expected fingerprints. For example, suppose someone sends or emails you a certificate that you put it in a file named \tmp\cert. Wraps the public key in an X.509 v3 self-signed certificate, which is stored as a single-element certificate chain. Validity period: Each certificate is valid only for a limited amount of time. For such commands, when the -storepass option isnt provided at the command line, the user is prompted for it. If a password is not provided, then the user is prompted for it. The KeyStore class provided in the java.security package supplies well-defined interfaces to access and modify the information in a keystore. If -srckeypass isnt provided, then the keytool command attempts to use -srcstorepass to recover the entry. It prints its contents in a human-readable format. For example, here is the format of the -printcert command: When you specify a -printcert command, replace cert_file with the actual file name, such as: keytool -printcert -file VScert.cer. The following are the available options for the -genseckey command: {-providerclass class [-providerarg arg]}: Add security provider by fully qualified class name with an optional configure argument. If the source entry is protected by a password, then -srckeypass is used to recover the entry. The value of the security provider is the name of a security provider that is defined in a module. When -rfc is specified, the output format is Base64-encoded PEM; otherwise, a binary DER is created. If the attempt fails, then the user is prompted for a password. The following are the available options for the -printcert command: {-sslserver server[:port]}: Secure Sockets Layer (SSL) server host and port. At times, it might be necessary to remove existing entries of certificates in a Java keystore. Before you add the certificate to the keystore, the keytool command verifies it by attempting to construct a chain of trust from that certificate to a self-signed certificate (belonging to a root CA), using trusted certificates that are already available in the keystore. Use the -exportcert command to read a certificate from the keystore that is associated with -alias alias and store it in the cert_file file. {-protected }: Password provided through a protected mechanism. As a result, e1 should contain ca, ca1, and ca2 in its certificate chain: The following are the available options for the -genkeypair command: {-groupname name}: Group name. Be very careful to ensure the certificate is valid before importing it as a trusted certificate. If such an attack took place, and you didnt check the certificate before you imported it, then you would be trusting anything the attacker signed, for example, a JAR file with malicious class files inside. The following are the available options for the -importkeystore command: {-srckeystore keystore}: Source keystore name, {-destkeystore keystore}: Destination keystore name, {-srcstoretype type}: Source keystore type, {-deststoretype type}: Destination keystore type, [-srcstorepass arg]: Source keystore password, [-deststorepass arg]: Destination keystore password, {-srcprotected Source keystore password protected, {-destprotected}: Destination keystore password protected, {-srcprovidername name}: Source keystore provider name, {-destprovidername name}: Destination keystore provider name, [-destkeypass arg]: Destination key password, {-providerclass class [-providerarg arg]}: Add security provider by fully qualified class name with an optional configure argument. Commands for keytool include the following: -certreq: Generates a certificate request, -gencert: Generates a certificate from a certificate request, -importcert: Imports a certificate or a certificate chain, -importkeystore: Imports one or all entries from another keystore, -keypasswd: Changes the key password of an entry, -printcert: Prints the content of a certificate, -printcertreq: Prints the content of a certificate request, -printcrl: Prints the content of a Certificate Revocation List (CRL) file, -storepasswd: Changes the store password of a keystore. That is, there is a corresponding abstract KeystoreSpi class, also in the java.security package, which defines the Service Provider Interface methods that providers must implement. A password shouldnt be specified on a command line or in a script unless it is for testing purposes, or you are on a secure system. The -exportcert command by default outputs a certificate in binary encoding, but will instead output a certificate in the printable encoding format, when the -rfc option is specified. If a file is not specified, then the CSR is output to -stdout. The option can appear multiple times. Use the -genseckey command to generate a secret key and store it in a new KeyStore.SecretKeyEntry identified by alias. Use the -certreq command to generate a Certificate Signing Request (CSR) using the PKCS #10 format. However, a password shouldnt be specified on a command line or in a script unless it is for testing, or you are on a secure system. It generates v3 certificates. You use the keytool command and options to manage a keystore (database) of cryptographic keys, X.509 certificate chains, and trusted certificates. For example, suppose someone sends or emails you a certificate that you put it in a file named /tmp/cert. Both reply formats can be handled by the keytool command. Typically, a key stored in this type of entry is a secret key, or a private key accompanied by the certificate chain for the corresponding public key. There are many public Certification Authorities, such as DigiCert, Comodo, Entrust, and so on. The -help command is the default. The new name, -importcert, is preferred. A CSR is intended to be sent to a CA. In its printable encoding format, the encoded certificate is bounded at the beginning and end by the following text: X.500 Distinguished Names are used to identify entities, such as those that are named by the subject and issuer (signer) fields of X.509 certificates. The names arent case-sensitive. A certificate from a CA is usually self-signed or signed by another CA. Keytool is a certificate management utility included with Java. Used to identify a cryptographic service provider's name when listed in the security properties file. If such an attack takes place, and you didnt check the certificate before you imported it, then you would be trusting anything that the attacker signed. For example, if a certificate has the KeyUsage extension marked critical and set to keyCertSign, then when this certificate is presented during SSL communication, it should be rejected because the certificate extension indicates that the associated private key should only be used for signing certificates and not for SSL use. Example. Submit myname.csr to a CA, such as DigiCert. If the alias doesnt point to a key entry, then the keytool command assumes you are adding a trusted certificate entry. All you do is import the new certificate using the same alias as the old one. {-protected}: Password provided through a protected mechanism. The following notes apply to the descriptions in Commands and Options: All command and option names are preceded by a hyphen sign (-). For example, you can use the alias duke to generate a new public/private key pair and wrap the public key into a self-signed certificate with the following command. The name argument can be a supported extension name (see Supported Named Extensions ) or an arbitrary OID number. Create a Self-Signed Certificate. If the reply is a PKCS #7 formatted certificate chain or a sequence of X.509 certificates, then the chain is ordered with the user certificate first followed by zero or more CA certificates. The following commands will help achieve the same. Currently, two command-line tools (keytool and jarsigner) make use of keystore implementations. The following example creates a certificate, e1, that contains three certificates in its certificate chain. Upload the PKCS#7 certificate file on the server. Signature algorithm identifier: This identifies the algorithm used by the CA to sign the certificate. The user can provide only one part, which means the other part is the same as the current date (or time). The keytool command can handle both types of entries, while the jarsigner tool only handles the latter type of entry, that is private keys and their associated certificate chains. Digitally Signed: If some data is digitally signed, then it is stored with the identity of an entity and a signature that proves that entity knows about the data.
