5 EVP_KDF-PVKKDF - The PVK EVP_KDF implementation
9 Support for computing the B<PVK KDF> PIN-based KDF through the B<EVP_KDF>
12 The EVP_KDF-PVKKDF algorithm implements a PVK PIN-based key
13 derivation function; it derives a key from a password using a salt.
17 "PVKKDF" is the name for this implementation; it
18 can be used with the EVP_KDF_fetch() function.
20 =head2 Supported parameters
22 The supported parameters are:
26 =item "pass" (B<OSSL_KDF_PARAM_PASSWORD>) <octet string>
28 =item "salt" (B<OSSL_KDF_PARAM_SALT>) <octet string>
30 =item "properties" (B<OSSL_KDF_PARAM_PROPERTIES>) <UTF8 string>
32 =item "digest" (B<OSSL_KDF_PARAM_DIGEST>) <UTF8 string>
34 These parameters work as described in L<EVP_KDF(3)/PARAMETERS>.
40 A typical application of this algorithm is to derive keying material for an
41 encryption algorithm from a password in the "pass" and a salt in "salt".
43 No assumption is made regarding the given password; it is simply treated as a
