I am trying to measure the running time of different crypto algorithm. e.g. how long it takes to encrypt/decrypt a block of plaintext. May I ask if C with OpenSSL is the best PL to do this?
By far, the language question is a matter of fashion. The best language for getting stuff done is the one you know. The best language for personal development is one you don’t.
C would work just fine.

The same (both PL and library) that you’d use for production because libraries differ in implementation details, and benchmark from one PL/library is not representative of performance with another PL.
