30.Sh DESCRIPTION
31.Fn RSA_PSS_PARAMS_new
32allocates and initializes an empty
33.Vt RSA_PSS_PARAMS
34object, representing an ASN.1
35.Vt RSASSA-PSS-params
36structure defined in RFC 8017 appendix A.2.3.
37It references the hash function and the mask generation function
38and stores the length of the salt and the trailer field number.

40frees
41.Fa params .
42.Sh RETURN VALUES
43.Fn RSA_PSS_PARAMS_new
44returns the new
45.Vt RSA_PSS_PARAMS
46object or
47.Dv NULL
48if an error occurs.
