Hi,

[this is going to a be shameless self advertising reply :) ...]

for AES, i'ld recommend you to read a recent post of mine "building a better
haskell aes" [1].
for RSA, to have something compatible my next suggestion for x509, you got
either RSA or cryptocipher [2].
for X509, everything you need is available in the certificate package [3]

While you mentioned performance is not your primary concern, I found that even
with medium use of crypto it becomes a significant bottleneck when using some
well established implementations.
