Function Documentation

◆ mbedtls_pkcs5_pbes2()

int mbedtls_pkcs5_pbes2 ( const mbedtls_asn1_buf pbe_params,
int  mode,
const unsigned char pwd,
size_t  pwdlen,
const unsigned char data,
size_t  datalen,
unsigned char output 
)

PKCS#5 PBES2 function.

Parameters
pbe_paramsthe ASN.1 algorithm parameters
modeeither MBEDTLS_PKCS5_DECRYPT or MBEDTLS_PKCS5_ENCRYPT
pwdpassword to use when generating key
pwdlenlength of password
datadata to process
datalenlength of data
outputoutput buffer
Returns
0 on success, or a MBEDTLS_ERR_XXX code if verification fails.

◆ mbedtls_pkcs5_pbkdf2_hmac()

int mbedtls_pkcs5_pbkdf2_hmac ( mbedtls_md_context_t ctx,

iteration_countIteration count
key_lengthLength of generated key in bytes
outputGenerated key. Must be at least as big as key_length
Returns
0 on success, or a MBEDTLS_ERR_XXX code if verification fails.
