Semantic CWT credentials

Verify a Semantic CWT credential by providing the encoded payload and specifying verification options.

You can provide a valid Semantic CWT credential as either an encoded string or a QR code in a PDF document or an image file.

Standard checks performed on all verification requests:

• Conformance of the string and encoded data. All string representations of CWT credentials must be prefixed with CSC/1.
• Decoded payload CWT structure and attributes can be validated.
• Remote context schema can be resolved and validate claims can be dereferenced.
• Issuer DID can be used to resolve its did.json document.
• Public key from issuer's did.json document validates the proof signature, confirming the credential has not been tampered with.

Optional parameter checks:

• Credential was issued by a trusted issuer.
• Current time is after the beginning of the credential validity period.
• Current time is not after the end of the credential validity period.
• Credential has not been revoked.
