Interface SecureTokenService
- All Known Implementing Classes:
DefaultSecureTokenService
public interface SecureTokenService
Service to Encrypt SecureTokenData into a short encrypted token and decrypt a token.
The encrypted string is in Base64 format. The data is signed and encrypted using 2 separate keys. The keys are
specified as hex character strings. Instances of this class are thread safe. Unlimited strength cryptography is
required. The data block is calculated as: Signature key (not included in data block) Length prefixed padding
SecureTokenData.Data SecureTokenData.Checksum SecureTokenData.TimeStamp padding MD5 signature of the above. All the
above (except signature key) is AES encrypted using encryption key. Result is base64ed.
