A context for HKDF can be obtained by calling:
- EVP_PKEY_CTX *pctx = EVP_PKEY_new_id(EVP_PKEY_HKDF, NULL);
+ EVP_PKEY_CTX *pctx = EVP_PKEY_CTX_new_id(EVP_PKEY_HKDF, NULL);
The total length of the info buffer cannot exceed 1024 bytes in length: this
should be more than enough for any normal use of HKDF.
/* Error */
if (EVP_PKEY_CTX_set1_hkdf_key(pctx, "secret", 6) <= 0)
/* Error */
- if (EVP_PKEY_CTX_add1_hkdf_info(pctx, "label", 6) <= 0)
+ if (EVP_PKEY_CTX_add1_hkdf_info(pctx, "label", 5) <= 0)
/* Error */
if (EVP_PKEY_derive(pctx, out, &outlen) <= 0)
/* Error */
