Field Detail

BASE64_ENCODED_KEY_ID

public static final JwtEcdsaParameters.KidStrategy BASE64_ENCODED_KEY_ID

The "kid" is the URL safe (RFC 4648 Section 5) base64-encoded big-endian key_id in the keyset.

In PublicKeySign#signAndEncode Tink always adds the KID.

In PublicKeyVerify#verifyAndDecode Tink checks that the kid is present and equal to this value.

This strategy is recommended by Tink.

IGNORED

public static final JwtEcdsaParameters.KidStrategy IGNORED

The "kid" header is ignored.

In PublicKeySign#signAndEncode Tink does not write a "kid" header.

In PublicKeyVerify#verifyAndDecode Tink ignores the "kid" header.

CUSTOM

public static final JwtEcdsaParameters.KidStrategy CUSTOM

The "kid" is fixed. It can be obtained from parameters.getCustomKid().

In PublicKeySign#signAndEncode Tink writes the "kid" header to the value given by parameters.getCustomKid().

In PublicKeyVerify#verifyAndDecode, if the kid is present, it needs to match parameters.getCustomKid(). If the kid is absent, it will be accepted.

Note: Tink does not allow to randomly generate new JwtEcdsaKey objects from parameters objects with KidStrategy equals to CUSTOM.
