In the case of RSA the signing algorithm could be specified as, for example, "SHA256withRSA". The algorithm name must be specified, as there is no default. The name of the Cryptography Package Provider is designated also by the Signature parameter to the constructor and the verify method. ...
For example, the Signature engine class provides access to the functionality of a digital signature algorithm. The actual implementation supplied in a SignatureSpi subclass (see next paragraph) would be that for a specific kind of signature algorithm, such as SHA256withDSA or SHA512withRSA. The...

including the RSA, DSA, and ECDSA signature algorithms, the AES encryption algorithm, the SHA-2 message digest algorithms, and the Diffie-Hellman (DH) and Elliptic Curve Diffie-Hellman (ECDH) key agreement algorithms. Most of the built-in providers implement cryptographic algorithms in Java code....
To implement a pair of Secret Key of Digital Signature Algorithm which was put forward by National Institute of Standards and Technology (NIST) by using Java Programming Language, the paper expounds the technology of DSA and the Programming Technology of building a pair of Secret Key of Digital...
如果已使用 MD2withRSA 之类的弱签名算法对本示例中的文件进行签名,则将显示以下输出:jar: beginEntry META-INF/my_sig.RSA jar: processEntry: processing block jar: processEntry caught: java.security.SignatureException: Signature check failed. Disabled algorithm used: MD2withRSA jar: done with meta! 更...
Disabled algorithm used: MD2withRSA jar: done with meta! 更新的 jarsigner 命令将退出,并将下面的警告输出到标准输出中:“签名无法解析或无法验证。jar 将被视为未签名。可能已使用当前已禁用的弱算法对 jar 进行了签名。有关详细信息,请在启用调试的情况下重新运行 jarsigner (-J-Djava.security.debug=jar)...
The performance of XML signature generation using the RSA algorithm on the Sun Fire T2000 server is four to five times that of Xeon. As the cryptographic key size increases, you can see a leap in the difference in performance. Conclusion Because XML technology has become an integral part of ...
