EVP_PKEY_CTX_set1_pbe_pass.3ossl - Man Page

generic KDF support functions


 #include <openssl/kdf.h>

 int EVP_PKEY_CTX_set1_pbe_pass(EVP_PKEY_CTX *pctx, unsigned char *pass,
                                int passlen);


These functions are generic support functions for all KDF algorithms.

EVP_PKEY_CTX_set1_pbe_pass() sets the password to the passlen first bytes from pass.

String CTRLS

There is also support for string based control operations via EVP_PKEY_CTX_ctrl_str(3). The password can be directly specified using the type parameter "pass" or given in hex encoding using the "hexpass" parameter.

Return Values

All these functions return 1 for success and 0 or a negative value for failure. In particular a return value of -2 indicates the operation is not supported by the public key algorithm.

EVP_PKEY_CTX_set1_pbe_pass() was converted from a macro to a function in OpenSSL 3.0.
