v1.0

1. PKCS1格式签名验签
2. CMS格式签名验签

Example:

DigestAlgorithm defaultDigestAlg = SignatureAlgorithmNameGenerator.getDefaultDigestAlg(signerKey);
Signer signer = new SimpleDigestSigner(signerKey, defaultDigestAlg);
byte[] signature = signer.sign(plaintext);

DigestAlgorithm defaultDigestAlg = SignatureAlgorithmNameGenerator.getDefaultDigestAlg(verifierKey);
Verifier verifier = new SimpleDigestVerifier(verifierKey, defaultDigestAlg);
boolean verified = verifier.verify(plaintext, signature);

DigestAlgorithm defaultDigestAlg = SignatureAlgorithmNameGenerator.getDefaultDigestAlg(signerKey);
CMSSigner signer = new SimpleCMSSigner(signerKey, signerCert, defaultDigestAlg); // default contract - contains signingTime attribute
byte[] cmsSignedData = signer.sign(content); // default sign - content detached

DigestAlgorithm defaultDigestAlg = SignatureAlgorithmNameGenerator.getDefaultDigestAlg(signerKey);
CMSSigner signer = new SimpleCMSSigner(signerKey, signerCert, defaultDigestAlg, true); // no signed attributes will be included
byte[] cmsSignedData = signer.sign(content, true); // the content should be encapsulated in the signature

CMSVerifier verifier = new SimpleCMSVerifier(signerCert);
boolean verified = verifier.verify(content, cmsSignedData); // verify detached signature

CMSVerifier verifier = new SimpleCMSVerifier(signerCert);
boolean verified = verifier.verify(cmsSignedData); // verify encapsulated signature
