Class WeakSignature
This API provides access to Deprecated algorithms.
See Signature for full documentation. WeakSignature is simply a drop-in replacement that only supports
deprecated algorithms. This is helpful when you need to deal with weak algorithms for backward compatibility
purposes, but Signature should always be used for new development and for anything intended to be secure.
This class allows access to signature services offered through the Java Cryptography Architecture (JCA). At this time
the signature/verification implementation of the methods is based on the default RSA JCE provider of the JDK -
sun.security.rsa.SunRsaSign
dw.crypto.WeakSignature is an adapter to the security provider implementation and only covers one digest algorithm:
Note: this class handles sensitive security-related data. Pay special attention to PCI DSS v3. requirements 2,
4, 12, and other relevant requirements.
