Tlsfuzzer

Tlsfuzzer is a cryptographic testing and fuzzing tool that targets TLS protocol implementations and related libraries such as ECDSA, surfacing timing-channel and input-handling weaknesses that are difficult to detect through standard functional testing. The recurring vulnerability classes—including covert timing channels, improper length-parameter handling, improper input validation, and observable timing discrepancies—reflect the precision required to validate both functional correctness and constant-time operation in cryptographic code. Current severity, exploitation, and exposure counts are shown alongside this summary.
