=head1 NAME
|
|
|
|
EVP_ASYM_CIPHER-RSA
|
|
- RSA Asymmetric Cipher algorithm support
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Asymmetric Cipher support for the B<RSA> key type.
|
|
|
|
=head2 RSA Asymmetric Cipher parameters
|
|
|
|
=over 4
|
|
|
|
=item "pad-mode" (B<OSSL_ASYM_CIPHER_PARAM_PAD_MODE>) <UTF8 string>
|
|
|
|
The default provider understands these RSA padding modes in string form:
|
|
|
|
=over 4
|
|
|
|
=item "none" (B<OSSL_PKEY_RSA_PAD_MODE_NONE>)
|
|
|
|
=item "oaep" (B<OSSL_PKEY_RSA_PAD_MODE_OAEP>)
|
|
|
|
=item "pkcs1" (B<OSSL_PKEY_RSA_PAD_MODE_PKCSV15>)
|
|
|
|
This padding mode is no longer supported by the FIPS provider for key
|
|
agreement and key transport.
|
|
(This is a FIPS 140-3 requirement)
|
|
|
|
=item "x931" (B<OSSL_PKEY_RSA_PAD_MODE_X931>)
|
|
|
|
=back
|
|
|
|
=item "pad-mode" (B<OSSL_ASYM_CIPHER_PARAM_PAD_MODE>) <integer>
|
|
|
|
The default provider understands these RSA padding modes in integer form:
|
|
|
|
=over 4
|
|
|
|
=item 1 (B<RSA_PKCS1_PADDING>)
|
|
|
|
This padding mode is no longer supported by the FIPS provider for key
|
|
agreement and key transport.
|
|
(This is a FIPS 140-3 requirement)
|
|
|
|
=item 3 (B<RSA_NO_PADDING>)
|
|
|
|
=item 4 (B<RSA_PKCS1_OAEP_PADDING>)
|
|
|
|
=item 5 (B<RSA_X931_PADDING>)
|
|
|
|
=back
|
|
|
|
See L<EVP_PKEY_CTX_set_rsa_padding(3)> for further details.
|
|
|
|
=item "digest" (B<OSSL_ASYM_CIPHER_PARAM_OAEP_DIGEST>) <UTF8 string>
|
|
|
|
=item "digest-props" (B<OSSL_ASYM_CIPHER_PARAM_OAEP_DIGEST_PROPS>) <UTF8 string>
|
|
|
|
=item "mgf1-digest" (B<OSSL_ASYM_CIPHER_PARAM_MGF1_DIGEST>) <UTF8 string>
|
|
|
|
=item "mgf1-digest-props" (B<OSSL_ASYM_CIPHER_PARAM_MGF1_DIGEST_PROPS>) <UTF8 string>
|
|
|
|
=item "oaep-label" (B<OSSL_ASYM_CIPHER_PARAM_OAEP_LABEL>) <octet string>
|
|
|
|
=item "tls-client-version" (B<OSSL_ASYM_CIPHER_PARAM_TLS_CLIENT_VERSION>) <unsigned integer>
|
|
|
|
See B<RSA_PKCS1_WITH_TLS_PADDING> on the page L<EVP_PKEY_CTX_set_rsa_padding(3)>.
|
|
|
|
=item "tls-negotiated-version" (B<OSSL_ASYM_CIPHER_PARAM_TLS_CLIENT_VERSION>) <unsigned integer>
|
|
|
|
See B<RSA_PKCS1_WITH_TLS_PADDING> on the page L<EVP_PKEY_CTX_set_rsa_padding(3)>.
|
|
|
|
See L<provider-asym_cipher(7)/Asymmetric Cipher Parameters> for more information.

|
The OpenSSL FIPS provider also supports the following parameters:
|
|
|
|
=over 4
|
|
|
|
=item "fips-indicator" (B<OSSL_ASYM_CIPHER_PARAM_FIPS_APPROVED_INDICATOR>) <integer>
|
|
|
|
=item "key-check" (B<OSSL_ASYM_CIPHER_PARAM_FIPS_KEY_CHECK>) <integer>
|
|
|
|
See L<provider-asym_cipher(7)/Asymmetric Cipher Parameters> for more information.
|
|
|
|
=item "pkcs15-pad-disabled" (B<OSSL_ASYM_CIPHER_PARAM_FIPS_RSA_PKCS15_PAD_DISABLED>) <integer>
|
|
|
|
The default value of 1 causes an error during encryption if the RSA padding
|
|
mode is set to "pkcs1".
|
|
Setting this to zero will ignore the error and set the approved
|
|
"fips-indicator" to 0.
|
|
This option breaks FIPS compliance if it causes the approved "fips-indicator"
|
|
to return 0.
