=head1 NAME
|
|
|
|
EVP_KDF-PVKKDF - The PVK EVP_KDF implementation
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Support for computing the B<PVK KDF> PIN-based KDF through the B<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.
|
|
|
|
=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<OSSL_KDF_PARAM_PASSWORD>) <octet string>
|
|
|
|
=item "salt" (B<OSSL_KDF_PARAM_SALT>) <octet string>
|
|
|
|
=item "properties" (B<OSSL_KDF_PARAM_PROPERTIES>) <UTF8 string>
|
|
|
|
=item "digest" (B<OSSL_KDF_PARAM_DIGEST>) <UTF8 string>
|
|
|
|
These parameters work as described in L<EVP_KDF(3)/PARAMETERS>.

|
=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.
