See L<EVP_PKEY_encapsulate(3)> and L<EVP_PKEY_decapsulate(3)> for more details about basic KEM operations. =head2 ML-KEM KEM parameters =over 4 =item "ikme" (B<OSSL_KEM_PARAM_IKME>) <octet string> The OpenSSL ML-KEM encapsulation mechanism can only be modified by setting randomness during encapsulation, this enables testing, as per FIPS 203, section 6.2, algorithm 17. This parameter should not be used for purposes other than testing. When this parameter is not set, encapsulation proceeds as per FIPS 203, section 7.2 This parameter is only settable. =back This can be set when using EVP_PKEY_encapsulate_init(). =head1 CONFORMING TO =over 4 =item FIPS203 =back =head1 SEE ALSO L<EVP_PKEY_encapsulate(3)>, L<EVP_PKEY_decapsulate(3)>, L<EVP_KEYMGMT(3)>, L<EVP_PKEY(3)>, L<provider-keymgmt(7)> =head1 HISTORY This functionality was added in OpenSSL 3.5. =head1 COPYRIGHT Copyright 2024-2025 The OpenSSL Project Authors.
