EVP_PKEY_CTX_set1_pbe_pass - 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.


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.


All these functions are implemented as macros.


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.
