If the key in use has parameter restrictions then +the corresponding signature parameters are set to the restrictions: +for example, if the key can only be used with digest SHA256, MGF1 SHA256 +and minimum salt length 32 then the digest, MGF1 digest and salt length +will be set to SHA256, SHA256 and 32 respectively. + +=head2 Key Generation + +By default no parameter restrictions are placed on the generated key. + +=head1 NOTES + +The public key format is documented in RFC4055. + +The PKCS#8 private key format used for RSA-PSS keys is similar to the RSA +format except it uses the B<id-RSASSA-PSS> OID and the parameters field, if +present, restricts the key parameters in the same way as the public key. + +=head1 CONFORMING TO + +RFC 4055 + +=head1 SEE ALSO + +L<EVP_PKEY_CTX_set_rsa_pss_keygen_md(3)>, +L<EVP_PKEY_CTX_set_rsa_pss_keygen_mgf1_md(3)>, +L<EVP_PKEY_CTX_set_rsa_pss_keygen_saltlen(3)>, +L<EVP_PKEY_CTX_new(3)>, +L<EVP_PKEY_CTX_ctrl_str(3)>, +L<EVP_PKEY_derive(3)> + +=head1 COPYRIGHT + +Copyright 2017-2018 The OpenSSL Project Authors.
