Cryptology vs. Cryptography: What

WebCryptanalysis is the process of studying cryptographic systems to look for weaknesses or leaks of information. Cryptanalysis is generally thought of as exploring the weaknesses of the underlying mathematics of a cryptographic system but it also includes looking for weaknesses in implementation, such as side channel attacks or weak entropy inputs.
