Create a JWS JWT

A digitally signed or MACed JWT

Acquire the default validation settings.

RFC 7519 §4.1.3. states that applications MUST identify itself with a value in the audience claim, therefore a predicate must be supplied.

The other defaults are:

• defaultValidationSettings for JWS verification
• Zero clock skew tolerance when validating nbf, exp and iat claims
• iat claim is checked
• issuer claim is not checked

Cryptographically verify a JWS JWT, then validate the Claims Set, returning it if valid.

This is the only way to get at the claims of a JWS JWT, enforcing that the claims are cryptographically and semantically valid before the application can use them.

See also verifyClaimsAt which allows you to explicitly specify the time.

Cryptographically verify a JWS JWT, then validate the Claims Set, returning it if valid.

This is the same as verifyClaims except that the time is explicitly provided. If you process many requests per second this will allow you to avoid unnecessary repeat system calls.

Maximum allowed skew when validating the nbf, exp and iat claims.

Predicate for checking values in the aud claim.

Predicate for checking the iss claim.

Whether to check that the iat claim is not in the future.

The JWT Claims Set represents a JSON object whose members are the registered claims defined by RFC 7519. Unrecognised claims are gathered into the unregisteredClaims map.

The audience claim identifies the recipients that the JWT is intended for. Each principal intended to process the JWT MUST identify itself with a value in the audience claim. If the principal processing the claim does not identify itself with a value in the aud claim when this claim is present, then the JWT MUST be rejected.

The expiration time claim identifies the expiration time on or after which the JWT MUST NOT be accepted for processing. The processing of exp claim requires that the current date/time MUST be before expiration date/time listed in the exp claim. Implementers MAY provide for some small leeway, usually no more than a few minutes, to account for clock skew.

The issued at claim identifies the time at which the JWT was issued. This claim can be used to determine the age of the JWT.

The issuer claim identifies the principal that issued the JWT. The processing of this claim is generally application specific.

The JWT ID claim provides a unique identifier for the JWT. The identifier value MUST be assigned in a manner that ensures that there is a negligible probability that the same value will be accidentally assigned to a different data object. The jti claim can be used to prevent the JWT from being replayed. The jti value is a case-sensitive string.

The not before claim identifies the time before which the JWT MUST NOT be accepted for processing. The processing of the nbf claim requires that the current date/time MUST be after or equal to the not-before date/time listed in the nbf claim. Implementers MAY provide for some small leeway, usually no more than a few minutes, to account for clock skew.

The subject claim identifies the principal that is the subject of the JWT. The Claims in a JWT are normally statements about the subject. The subject value MAY be scoped to be locally unique in the context of the issuer or MAY be globally unique. The processing of this claim is generally application specific.

Claim Names can be defined at will by those using JWTs.

Return an empty claims set.

Validate the claims made by a ClaimsSet.

These checks are performed by verifyClaims, which also validates any signatures, so you shouldn't need to use this function directly.

Audience data. In the general case, the aud value is an array of case-sensitive strings, each containing a StringOrURI value. In the special case when the JWT has one audience, the aud value MAY be a single case-sensitive string containing a StringOrURI value.

The ToJSON instance formats an Audience with one value as a string (some non-compliant implementations require this.)

A JSON string value, with the additional requirement that while arbitrary string values MAY be used, any value containing a : character MUST be a URI.

Note: the IsString instance will fail if the string contains a : but does not parse as a URI. Use stringOrUri directly in this situation.

A JSON numeric value representing the number of seconds from 1970-01-01T0:0:0Z UTC until the specified UTC date/time.
