<br>Hi,
<br>
<br>[this is going to a be shameless self advertising reply :) ...]
<br>
<br>for AES, i'ld recommend you to read a recent post of mine "building a better
<br>haskell aes" [1].
<br>for RSA, to have something compatible my next suggestion for x509, you got
<br>either RSA or cryptocipher [2].
<br>for X509, everything you need is available in the certificate package [3]
<br>
<br>While you mentioned performance is not your primary concern, I found that even
<br>with medium use of crypto it becomes a significant bottleneck when using some
<br>well established implementations.
