Unverified50% confidenceFactExact time
When a validator only checks whether the cryptographic signature matches without checking whether the exclusion range covers the actual content, the signature may be mathematically valid but cover zero bytes, leaving the content entirely unprotected.

UnverifiedSignature verification must not only check the signature value itself, but must also enforce a locked list of allowed algorithms, rather than trusting the algorithm declared in the token header.73% similarUnverifiedA common mistake in signature verification is asking only "is the signature valid?" rather than "what does the signature cover?"73% similarUnverifiedThe key criterion for verifying whether a credential vault is effective is this: when an agent uses a secret, the value does not appear in the conversation record; if it does, the vault is merely decoration.70% similarUnverifiedWatermarks and cryptographic signatures are not competing but complementary: watermarks hide information within the content itself so that traces are retained even if metadata is lost, while signatures provide richer, human-readable provenance information.70% similar
