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)
  2. (RSA_NO_PADDING)
  3. (RSA_PKCS1_OAEP_PADDING)
  4. (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 provider-asym_cipher(7)/Asymmetric Cipher Parameters for more information.
