Declared in <openssl/pkcs12.h>

int
PKCS12_key_gen_asc(
    char const* pass,
    int passlen,
    unsigned char* salt,
    int saltlen,
    int id,
    int iter,
    int n,

Parameters

Name

Description

pass

ASCII passphrase.

passlen

Length of pass, or ‐1 to use strlen().

salt

Salt for derivation.

saltlen

Length of salt in bytes.

id

Purpose byte (PKCS12_KEY_ID, PKCS12_IV_ID, or PKCS12_MAC_ID).

iter

Iteration count (values less than 1 are treated as 1).

n

Number of bytes to derive.

out

Buffer to receive derived key material.

md_type

Message digest for the derivation.
