#include <openssl/crmf.h> int OSSL_CRMF_pbm_new(OSSL_LIB_CTX *libctx, const char *propq, const OSSL_CRMF_PBMPARAMETER *pbmp, const unsigned char *msg, size_t msglen, const unsigned char *sec, size_t seclen, unsigned char **mac, size_t *maclen); OSSL_CRMF_PBMPARAMETER *OSSL_CRMF_pbmp_new(OSSL_LIB_CTX *libctx, size_t saltlen, int owfnid, size_t itercnt, int macnid);
OSSL_CRMF_pbmp_new() initializes and returns a new PBMParameter structure with a new random salt of given length saltlen, OWF (one-way function) NID owfnid, OWF iteration count itercnt, and MAC NID macnid. The library context libctx parameter may be used to select the provider for the random number generation (DRBG) and may be NULL for the default.
RFC 4210 recommends that the salt SHOULD be at least 8 bytes (64 bits) long, where 16 bytes is common.
The iteration count must be at least 100, as stipulated by RFC 4211, and is limited to at most 100000 to avoid DoS through manipulated or otherwise malformed input.
OSSL_CRMF_pbmp_new() returns a new and initialized OSSL_CRMF_PBMPARAMETER structure, or NULL on error.
OSSL_CRMF_PBMPARAMETER *pbm = NULL; unsigned char *msg = "Hello"; unsigned char *sec = "SeCrEt"; unsigned char *mac = NULL; size_t maclen; if ((pbm = OSSL_CRMF_pbmp_new(16, NID_sha256, 500, NID_hmac_sha1) == NULL)) goto err; if (!OSSL_CRMF_pbm_new(pbm, msg, 5, sec, 6, &mac, &maclen)) goto err;
