No. RSA is not supported at all.

👍 RSA has been an ongoing source of problems and I am glad libsodium doesn't support it. Just yesterday OpenSSL saw both Bleichenbacher attacks and cache timing attacks against an alleged "constant time" RSA implementation that wasn't.

And because we’ll never get people to do that [i.e. use RSA securely], the simpler message is: abandon RSA altogether.

@maiermic Have you considered upgrading to crypto_box() / crypto_sign()? :)

Unfortunately, I have no choice in my current work, but I will consider it next time.
