NAME¶

RSA_PSS_PARAMS_new, RSA_PSS_PARAMS_free — probabilistic signature scheme with RSA hashing

SYNOPSIS¶

#include <openssl/rsa.h>

RSA_PSS_PARAMS *
RSA_PSS_PARAMS_new(void);

void
RSA_PSS_PARAMS_free(RSA_PSS_PARAMS *params);

DESCRIPTION¶

RSA_PSS_PARAMS_new() allocates and initializes an empty RSA_PSS_PARAMS object, representing an ASN.1 RSASSA-PSS-params structure defined in RFC 8017 appendix A.2.3. It references the hash function and the mask generation function and stores the length of the salt and the trailer field number. RSA_PSS_PARAMS_free() frees params.

RETURN VALUES¶

RSA_PSS_PARAMS_new() returns the new RSA_PSS_PARAMS object or NULL if an error occurs.

HISTORY¶

RSA_PSS_PARAMS_new() and RSA_PSS_PARAMS_free() first appeared in OpenSSL 1.0.1 and have been available since OpenBSD 5.3.
