EVP_ASYM_CIPHER-RSA(7)              OpenSSL             EVP_ASYM_CIPHER-RSA(7)



NAME
       EVP_ASYM_CIPHER-RSA - RSA Asymmetric Cipher algorithm support

DESCRIPTION
       Asymmetric Cipher support for the RSA key type.

   RSA Asymmetric Cipher parameters
       "pad-mode" (OSSL_ASYM_CIPHER_PARAM_PAD_MODE) <UTF8 string>
           The default provider understands these RSA padding modes in string
           form:

           "none" (OSSL_PKEY_RSA_PAD_MODE_NONE)
           "oaep" (OSSL_PKEY_RSA_PAD_MODE_OAEP)
           "pkcs1" (OSSL_PKEY_RSA_PAD_MODE_PKCSV15)
           "x931" (OSSL_PKEY_RSA_PAD_MODE_X931)
       "pad-mode" (OSSL_ASYM_CIPHER_PARAM_PAD_MODE) <integer>
           The default provider understands these RSA padding modes in integer
           form:

           1 (RSA_PKCS1_PADDING)
           3 (RSA_NO_PADDING)
           4 (RSA_PKCS1_OAEP_PADDING)
           5 (RSA_X931_PADDING)

           See EVP_PKEY_CTX_set_rsa_padding(3) for further details.

       "digest" (OSSL_ASYM_CIPHER_PARAM_OAEP_DIGEST) <UTF8 string>
       "digest-props" (OSSL_ASYM_CIPHER_PARAM_OAEP_DIGEST_PROPS) <UTF8 string>
       "mgf1-digest" (OSSL_ASYM_CIPHER_PARAM_MGF1_DIGEST) <UTF8 string>
       "mgf1-digest-props" (OSSL_ASYM_CIPHER_PARAM_MGF1_DIGEST_PROPS) <UTF8
       string>
       "oaep-label" (OSSL_ASYM_CIPHER_PARAM_OAEP_LABEL) <octet string>
       "tls-client-version" (OSSL_ASYM_CIPHER_PARAM_TLS_CLIENT_VERSION)
       <unsigned integer>
           See RSA_PKCS1_WITH_TLS_PADDING on the page
           EVP_PKEY_CTX_set_rsa_padding(3).

       "tls-negotiated-version" (OSSL_ASYM_CIPHER_PARAM_TLS_CLIENT_VERSION)
       <unsigned integer>
           See RSA_PKCS1_WITH_TLS_PADDING on the page
           EVP_PKEY_CTX_set_rsa_padding(3).

           See "Asymmetric Cipher Parameters" in provider-asym_cipher(7) for
           more information.
