EVP_KDF−PVKKDF − The PVK EVP_KDF implementation
Support for computing the PVK KDF PIN-based KDF through the EVP_KDF API.
The EVP_KDF−PVKKDF algorithm implements a PVK PIN-based key derivation function; it derives a key from a password using a salt.
Identity
" PVKKDF" is the name for this
implementation; it can be used with the
EVP_KDF_fetch() function.
Supported
parameters
The supported parameters are:
"pass" (
OSSL_KDF_PARAM_PASSWORD ) <octet
string>
"salt" ( OSSL_KDF_PARAM_SALT
) <octet string>
"properties" (
OSSL_KDF_PARAM_PROPERTIES ) <
UTF8 string>
"digest" (
OSSL_KDF_PARAM_DIGEST ) <
UTF8 string>
These parameters work as described in " PARAMETERS" in EVP_KDF (3).
A typical application of this algorithm is to derive keying material for an encryption algorithm from a password in the "pass" and a salt in "salt".
No assumption is made regarding the given password; it is simply treated as a byte sequence.
The legacy provider needs to be available in order to access this algorithm.
EVP_KDF (3), EVP_KDF_CTX_new(3), EVP_KDF_CTX_free(3), EVP_KDF_CTX_set_params(3), EVP_KDF_derive(3), " PARAMETERS" in EVP_KDF (3), OSSL_PROVIDER−legacy(7)
