Function Documentation

int mbedtls_pkcs12_derivation ( unsigned char *  data,
size_t  datalen,
const unsigned char *  pwd,
size_t  pwdlen,
const unsigned char *  salt,
size_t  saltlen,
mbedtls_md_type_t  mbedtls_md,
int  id,
int  iterations 
)

The PKCS#12 derivation function uses a password and a salt to produce pseudo-random bits for a particular "purpose".

Depending on the given id, this function can produce an encryption/decryption key, an nitialization vector or an integrity key.

Parameters
databuffer to store the derived data in
datalenlength to fill
pwdpassword to use (may be NULL if no password is used)
pwdlenlength of the password (may be 0)
saltsalt buffer to use
saltlenlength of the salt
mbedtls_mdmbedtls_md type to use during the derivation
idid that describes the purpose (can be MBEDTLS_PKCS12_DERIVE_KEY, MBEDTLS_PKCS12_DERIVE_IV or MBEDTLS_PKCS12_DERIVE_MAC_KEY)
iterationsnumber of iterations
Returns
0 if successful, or a MD, BIGNUM type error.

md_typethe mbedtls_md used
pwdthe password used (may be NULL if no password is used)
pwdlenlength of the password (may be 0)
inputthe input data
lendata length
outputthe output buffer
Returns
0 if successful, or a MBEDTLS_ERR_XXX code
