List of verifySignature() Examples

Examples of verifySignature()

com.cloud.bridge.util.EC2RestAuth.verifySignature()
The request is authenticated if we can regenerate the same signature given on the request. Before calling this function make sure to set the header values defined by the public values above. @param httpVerb - the type of HTTP request (e.g., GET, PUT) @param secretKey - value obtained from the AWSAccessKeyId @param signature - the signature we are trying to recreate, note can be URL-encoded @param method - { "HmacSHA1", "HmacSHA256" } @throws SignatureException @return true if request has been authenticated, false otherwise @throws UnsupportedEncodingException

com.itextpdf.text.pdf.AcroFields.verifySignature()

Verifies a signature. An example usage is:

 KeyStore kall = PdfPKCS7.loadCacertsKeyStore(); PdfReader reader = new PdfReader("my_signed_doc.pdf"); AcroFields af = reader.getAcroFields(); ArrayList names = af.getSignatureNames(); for (int k = 0; k < names.size(); ++k) { String name = (String)names.get(k); System.out.println("Signature name: " + name); System.out.println("Signature covers whole document: " + af.signatureCoversWholeDocument(name)); PdfPKCS7 pk = af.verifySignature(name); Calendar cal = pk.getSignDate(); Certificate pkc[] = pk.getCertificates(); System.out.println("Subject: " + PdfPKCS7.getSubjectFields(pk.getSigningCertificate())); System.out.println("Document modified: " + !pk.verify()); Object fails[] = PdfPKCS7.verifyCertificates(pkc, kall, null, cal); if (fails == null) System.out.println("Certificates verified against the KeyStore"); else System.out.println("Certificate failed: " + fails[1]); }

@param name the signature field name @return a PdfPKCS7 class to continue the verification

com.lowagie.text.pdf.AcroFields.verifySignature()

Verifies a signature. An example usage is:

 KeyStore kall = PdfPKCS7.loadCacertsKeyStore(); PdfReader reader = new PdfReader("my_signed_doc.pdf"); AcroFields af = reader.getAcroFields(); ArrayList names = af.getSignatureNames(); for (int k = 0; k < names.size(); ++k) { String name = (String)names.get(k); System.out.println("Signature name: " + name); System.out.println("Signature covers whole document: " + af.signatureCoversWholeDocument(name)); PdfPKCS7 pk = af.verifySignature(name); Calendar cal = pk.getSignDate(); Certificate pkc[] = pk.getCertificates(); System.out.println("Subject: " + PdfPKCS7.getSubjectFields(pk.getSigningCertificate())); System.out.println("Document modified: " + !pk.verify()); Object fails[] = PdfPKCS7.verifyCertificates(pkc, kall, null, cal); if (fails == null) System.out.println("Certificates verified against the KeyStore"); else System.out.println("Certificate failed: " + fails[1]); }

@param name the signature field name @return a PdfPKCS7 class to continue the verification

com.subgraph.orchid.crypto.TorPublicKey.verifySignature()
de.anomic.tools.CryptoLib.verifySignature()
org.apache.harmony.xnet.provider.jsse.DigitalSignature.verifySignature()
Verifies the signature data. @param data - the signature bytes @return true if verified
org.apache.poi.poifs.crypt.dsig.SignatureInfo.verifySignature()
@return true, if first signature part is valid
org.apache.ws.security.saml.ext.AssertionWrapper.verifySignature()
Verify the signature of this assertion @throws ValidationException
org.apache.wss4j.common.saml.SamlAssertionWrapper.verifySignature()
Verify the signature of this assertion @throws ValidationException
org.bouncycastle.crypto.Signer.verifySignature()
return true if the internal state represents the signature described in the passed in array.
org.bouncycastle.crypto.signers.DSASigner.verifySignature()
return true if the value r and s represent a DSA signature for the passed in message for standard DSA the message should be a SHA-1 hash of the real message to be verified.
org.bouncycastle.crypto.signers.ECDSASigner.verifySignature()
return true if the value r and s represent a DSA signature for the passed in message (for standard DSA the message should be a SHA-1 hash of the real message to be verified).
org.bouncycastle.crypto.signers.ISO9796d2PSSSigner.verifySignature()
return true if the signature represents a ISO9796-2 signature for the passed in message.
org.bouncycastle.crypto.signers.ISO9796d2Signer.verifySignature()
return true if the signature represents a ISO9796-2 signature for the passed in message.
org.bouncycastle.crypto.signers.PSSSigner.verifySignature()
return true if the internal state represents the signature described in the passed in array.
org.certificatetransparency.ctlog.LogSignatureVerifier.verifySignature()
Verifies the CT Log's signature over the SCT and certificate. Works for the following cases: * Ordinary X509 certificate sent to the log. * PreCertificate signed by an ordinary CA certificate. * PreCertificate signed by a PreCertificate Signing Cert. In this case the PreCertificate signing certificate must be 2nd on the chain, the CA cert itself 3rd. It does not work for verifying a final certificate with the CT extension. TODO(eranm): Add the ability to remove the CT extension and verify a final certificate. @param sct SignedCertificateTimestamp received from the log. @param chain The certificates chain as sent to the log. @return true if the log's signature over this SCT can be verified, false otherwise.
org.jose4j.jws.JsonWebSignature.verifySignature()
org.openid4java.association.Association.verifySignature()
org.spongycastle.crypto.signers.ECDSASigner.verifySignature()
test.javax.management.compliance.signature.support.SignatureVerifier.verifySignature()
