1=pod 2 3=head1 NAME 4 5EVP_KDF-X942-CONCAT - The X942 Concat EVP_KDF implementation 6 7=head1 DESCRIPTION 8 9The EVP_KDF-X942-CONCAT algorithm is identical to EVP_KDF-X963. It is 10used for key agreement to derive a key using input such as a shared secret key 11and shared info. 12 13=head2 Identity 14 15"X942KDF_CONCAT" is the name for this implementation; it 16can be used with the EVP_KDF_fetch() function. 17 18This is an alias for "X963KDF". 19 20See L<EVP_KDF-X963(7)> for a list of supported parameters and examples. 21 22=head1 HISTORY 23 24This functionality was added in OpenSSL 3.0. 25 26=head1 COPYRIGHT 27 28Copyright 2020-2021 The OpenSSL Project Authors.
