@Beta
public class IdToken
extends JsonWebSignature

Beta
ID token as described in ID Token.

Use parse(JsonFactory, String) to parse an ID token from a string. Then, use the verify methods to verify the ID token as required by the specification.

Implementation is not thread-safe.

IdToken.Payload	getPayload()
static IdToken	parse(JsonFactory jsonFactory, String idTokenString) Parses the given ID token string and returns the parsed ID token.
boolean	verifyAudience(Collection<String> trustedClientIds) Returns whether the audience in the payload contains only client IDs that are trusted as specified in step 2 of ID Token Validation.
boolean	verifyExpirationTime(long currentTimeMillis, long acceptableTimeSkewSeconds) Returns whether the JsonWebToken.Payload.getExpirationTimeSeconds() is valid relative to the current time, allowing for a clock skew as specified in step 5 of ID Token Validation.
boolean	verifyIssuedAtTime(long currentTimeMillis, long acceptableTimeSkewSeconds) Returns whether the JsonWebToken.Payload.getIssuedAtTimeSeconds() is valid relative to the current time, allowing for a clock skew as specified in step 6 of ID Token Validation.
boolean	verifyIssuer(Collection<String> expectedIssuer) Returns whether the issuer in the payload matches the given expected issuer as specified in step 1 of ID Token Validation.
boolean	verifyIssuer(String expectedIssuer) Returns whether the issuer in the payload matches the given expected issuer as specified in step 1 of ID Token Validation.
boolean	verifyTime(long currentTimeMillis, long acceptableTimeSkewSeconds) Returns whether the JsonWebToken.Payload.getExpirationTimeSeconds() and JsonWebToken.Payload.getIssuedAtTimeSeconds() are valid relative to the current time, allowing for a clock skew as specified in steps 5 and 6 of ID Token Validation.

Constructor Detail

IdToken

public IdToken(JsonWebSignature.Header header,
               IdToken.Payload payload,
               byte[] signatureBytes,
               byte[] signedContentBytes)

Parameters:

header - header

payload - payload

signatureBytes - bytes of the signature

signedContentBytes - bytes of the signature content

Method Detail

getPayload

public IdToken.Payload getPayload()

Overrides:

getPayload in class JsonWebToken

verifyIssuer

public final boolean verifyIssuer(String expectedIssuer)

Returns whether the issuer in the payload matches the given expected issuer as specified in step 1 of ID Token Validation.

Parameters:

expectedIssuer - expected issuer

verifyIssuer

public final boolean verifyIssuer(Collection<String> expectedIssuer)

Returns whether the issuer in the payload matches the given expected issuer as specified in step 1 of ID Token Validation. When an issuer is migrating to a new issuer string the expected issuer has multiple aliases, so multiple are permitted here.

Since:

1.21.0

verifyAudience

public final boolean verifyAudience(Collection<String> trustedClientIds)

Returns whether the audience in the payload contains only client IDs that are trusted as specified in step 2 of ID Token Validation.

Parameters:

trustedClientIds - list of trusted client IDs

verifyTime

public final boolean verifyTime(long currentTimeMillis,
                                long acceptableTimeSkewSeconds)

Returns whether the JsonWebToken.Payload.getExpirationTimeSeconds() and JsonWebToken.Payload.getIssuedAtTimeSeconds() are valid relative to the current time, allowing for a clock skew as specified in steps 5 and 6 of ID Token Validation.

Parameters:

currentTimeMillis - current time in milliseconds (typically System.currentTimeMillis())

acceptableTimeSkewSeconds - seconds of acceptable clock skew

verifyExpirationTime

public final boolean verifyExpirationTime(long currentTimeMillis,
                                          long acceptableTimeSkewSeconds)

Returns whether the JsonWebToken.Payload.getExpirationTimeSeconds() is valid relative to the current time, allowing for a clock skew as specified in step 5 of ID Token Validation.

Parameters:

currentTimeMillis - current time in milliseconds (typically System.currentTimeMillis())

acceptableTimeSkewSeconds - seconds of acceptable clock skew

verifyIssuedAtTime

public final boolean verifyIssuedAtTime(long currentTimeMillis,
                                        long acceptableTimeSkewSeconds)

Returns whether the JsonWebToken.Payload.getIssuedAtTimeSeconds() is valid relative to the current time, allowing for a clock skew as specified in step 6 of ID Token Validation.

Parameters:

currentTimeMillis - current time in milliseconds (typically System.currentTimeMillis())

acceptableTimeSkewSeconds - seconds of acceptable clock skew

parse

public static IdToken parse(JsonFactory jsonFactory,
                            String idTokenString)
                     throws IOException

Parses the given ID token string and returns the parsed ID token.

Parameters:

jsonFactory - JSON factory

idTokenString - ID token string

Returns:

parsed ID token

Throws:

IOException
