NAME

OSSL_PROVIDER-legacy - OpenSSL legacy provider

DESCRIPTION

The OpenSSL legacy provider supplies OpenSSL implementations of algorithms that have been deemed legacy. Such algorithms have commonly fallen out of use, have been deemed insecure by the cryptography community, or something similar.

We can consider this the retirement home of cryptographic algorithms.

Properties

The implementations in this provider specifically have these property defined:

"provider=legacy"

It may be used in a property query string with fetching functions such as EVP_CIPHER_fetch(3), as well as with other functions that take a property query string, such as OPERATIONS AND ALGORITHMS

The OpenSSL legacy provider supports these operations and algorithms:

MD2, see MD4, see MDC2, see WHIRLPOOL, see RIPEMD160, see SEE ALSO

openssl-core.h(7), provider(7)
