Subject: expose aes-{128,256}-cfb
|
|
|
|
This exposes AES-CFB ciphers through the EVP APIs. BoringSSL has
|
|
implementations for these ciphers, but Node doesn't realise that because
|
|
without this patch, they're not listed in the APIs that Node uses.
|
|
|
|
This should be upstreamed. See e.g.
|
|
https://boringssl-review.googlesource.com/c/boringssl/+/33984 for a
|
|
similar patch that was merged upstream.
