openssl_csr_new() generates a new CSR (Certificate Signing Request) based on the information provided by dn, which represents the Distinguished Name to be used in the certificate.
privkey should be set to a private key that was previously generated by openssl_pkey_new() (or otherwise obtained from the other openssl_pkey family of functions). The corresponding public portion of the key will be used to sign the CSR.
extraattribs is used to specify additional configuration options for the CSR. Both dn and extraattribs are associative arrays whose keys are converted to OIDs and applied to the relevant part of the request.
Nota: You need to have a valid openssl.cnf installed for this function to operate correctly. See the notes under the installation section for more information.
By default, the information in your system openssl.conf is used to initialize the request; you can specify a configuration file section by setting the config_section_section key of configargs. You can also specify an alternative openssl configuration file by setting the value of the config key to the path of the file you want to use. The following keys, if present in configargs behave as their equivalents in the openssl.conf, as listed in the table below.
Tabella 1. Configuration overrides
configargs key | type | openssl.conf equivalent | description |
---|---|---|---|
digest_alg | string | default_md | Selects which digest method to use |
x509_extensions | string | x509_extensions | Selects which extensions should be used when creating an x509 certificate |
req_extensions | string | req_extensions | Selects which extensions should be used when creating a CSR |
private_key_bits | string | default_bits | Specifies how many bits should be used to generate a private key |
private_key_type | integer | none | Specifies the type of private key to create. This can be one of OPENSSL_KEYTYPE_DSA, OPENSSL_KEYTYPE_DH or OPENSSL_KEYTYPE_RSA. The default value is OPENSSL_KEYTYPE_RSA which is currently the only supported key type. |
encrypt_key | boolean | encrypt_key | Should an exported key (with passphrase) be encrypted? |
Restituisce TRUE in caso di successo, FALSE in caso di fallimento.
