In my day job I currently need to deal with a lot of cryptographic processing. For the tests I need to perform various cryptographic functions in haskell. these include:
* AES Encryption/Decryption (CBC-Mode) * RSA Public Key Encryption/Decryption * Certificate Handling
I'm having some difficulties finding the libraries to use and using them correctly. Performance is /not/ my primary concern...rather *correctness* and*ease of use*.
Haskell has some great cryptographic libs but for me it seems hard to judge what to use. The ones that seem appropriate are:
* The AES package (for symmetric encryption) * The RSA package (for public key cryptography)
certificate handling is s.th. I haven't found out about
* how to deal with Certificates (e.g. extract the public key from X.509 certificates)
is there a recommended package (packages) that suite my purpose?
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.
