=pod =head1 NAME EVP_KDF-PVKKDF - The PVK EVP_KDF implementation =head1 DESCRIPTION Support for computing the B PIN-based KDF through the B API. The EVP_KDF-PVKKDF algorithm implements a PVK PIN-based key derivation function; it derives a key from a password using a salt. =head2 Identity "PVKKDF" is the name for this implementation; it can be used with the EVP_KDF_fetch() function. =head2 Supported parameters The supported parameters are: =over 4 =item "pass" (B) =item "salt" (B) =item "properties" (B) =item "digest" (B) These parameters work as described in L. =back =head1 NOTES 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. =head1 SEE ALSO L, L, L, L, L, L, L =head1 HISTORY This functionality was added to OpenSSL 3.0. =head1 COPYRIGHT Copyright 2021 The OpenSSL Project Authors.
