WebCryptographic Weaknesses. From a cryptographic perspective, there are two main areas that need to be reviewed on a digital certificate: The key strength should be at least 2048 bits. The signature algorithm should be at least SHA-256. Legacy algorithms such as MD5 and SHA-1 should not be used. Validity WebThe ability of a cryptographic system to protect information from attack is called its strength. Strength depends on many factors, including: The secrecy of the key. The difficulty of guessing the key or trying out all possible keys (a key search). Longer keys are generally harder to guess or find.
