Method __builtin.Nettle.Hash()->emsa_pss_verify()

Method emsa_pss_verify

bool emsa_pss_verify(string(8bit) message, string(8bit) sign, int(1..) bits, int(0..)|void saltlen, function(string(8bit), int(0..):string(8bit))|void mgf)

Description

This is the algorithm used to verify in RSASSA-PSS (RFC 3447 section 9.1.2).

Parameter message

Message that was signed.

Parameter sign

Signature digest to verify.

Parameter bits

Number of significant bits in sign.

Parameter saltlen

Length of the salt used.

Parameter mgf

Mask generation function to use. Defaults to mgf1().

Returns

Returns 1 on success and 0 (zero) on failure.
