Title "RSA-PSS 7"
RSA-PSS 7 "2022-07-05" "1.1.1q" "OpenSSL"
For nroff, turn off justification. Always turn off hyphenation; it makesway too many mistakes in technical documents.
"NAME"
RSA-PSS - EVP_PKEY RSA-PSS algorithm support
"DESCRIPTION"
Header "DESCRIPTION" The RSA-PSS \s-1EVP_PKEY\s0 implementation is a restricted version of the \s-1RSA\s0
algorithm which only supports signing, verification and key generation
using \s-1PSS\s0 padding modes with optional parameter restrictions.
It has associated private key and public key formats.
This algorithm shares several control operations with the \s-1RSA\s0 algorithm but with some restrictions described below.
"Signing and Verification"
Subsection "Signing and Verification" Signing and verification is similar to the \s-1RSA\s0 algorithm except the
padding mode is always \s-1PSS.\s0 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 \s-1SHA256, MGF1 SHA256\s0
and minimum salt length 32 then the digest, \s-1MGF1\s0 digest and salt length
will be set to \s-1SHA256, SHA256\s0 and 32 respectively.
"Key Generation"
Subsection "Key Generation" By default no parameter restrictions are placed on the generated key.
"NOTES"
Header "NOTES" The public key format is documented in \s-1RFC4055.\s0
The PKCS#8 private key format used for RSA-PSS keys is similar to the \s-1RSA\s0 format except it uses the id-RSASSA-PSS \s-1OID\s0 and the parameters field, if present, restricts the key parameters in the same way as the public key.
