For nroff, turn off justification. Always turn off hyphenation; it makesway too many mistakes in technical documents.
"NAME"
OSSL_PROVIDER-legacy - OpenSSL legacy provider
"DESCRIPTION"
Header "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"
Subsection "Properties" The implementations in this provider specifically has this property
defined:
Item "provider=legacy" It may be used in a property query string with fetching functions such as \fBEVP_MD_fetch\|(3) or EVP_CIPHER_fetch\|(3), as well as with other functions that take a property query string, such as \fBEVP_PKEY_CTX_new_from_name\|(3).
It isn't mandatory to query for any of these properties, except to make sure to get implementations of this provider and none other.
"OPERATIONS AND ALGORITHMS"
Header "OPERATIONS AND ALGORITHMS" The OpenSSL legacy provider supports these operations and algorithms:
