WebCryptanalysis: An Overview . Cryptanalysis is the technique of examining cryptographic systems for flaws or information leakage. Cryptanalysis is commonly thought of as searching for flaws in a cryptographic system's core mathematics, but it also involves looking for flaws in implementation, such as side-channel attacks or weak entropy inputs.
