Legacy Provider – DES Support Missing in OpenSSL 3

After upgrading to OpenSSL 3, our system fails IKE negotiations that rely on DES and 3Des encryption. Investigation reveals that the legacy provider (which supplies DES support) is not loaded by default. In our environment, the global crypto initialization routine does not include an explicit call to load the legacy provider. As a result, calls such as EVP_CipherInit_ex() fail with an "unsupported" error for DES-CBC.
