signature

问题 I have some problems to verify the signature of a JWT token I get. The token is signed with HS256. The code where I try to create a signature to proof the received one is: JwtSecurityToken token = tokenHandler.ReadJwtToken(tokenString); byte[] keyBytes = Encoding.UTF8.GetBytes("secret"); HMACSHA256 hmac = new HMACSHA256(keyBytes); byte[] signatureBytes = hmac.ComputeHash(Encoding.UTF8.GetBytes(token.RawHeader + "." + token.RawPayload)); string signature = Convert.ToBase64String(signatureBytes

问题 I'm signing a document with token certificate: var cp = new Org.BouncyCastle.X509.X509CertificateParser(); var chain = new[] { cp.ReadCertificate(cert.RawData) }; var externalSignature = new X509Certificate2Signature(cert, "SHA-1"); var pdfReader = new PdfReader(origem); var signedPdf = new FileStream(destino, FileMode.Create); var pdfStamper = PdfStamper.CreateSignature(pdfReader, signedPdf, '\0'); var sig = pdfStamper.SignatureAppearance; sig.SetVisibleSignature(new Rectangle(50, 0, 500, 50

问题 I wrote a test program, and now it seems that if I don't use $/ in a method signature because I have to use .match inside the method, I can no long make anything. What did I do wrong? A further question is that if .match sets $/ , and $/ is read-only, then I cannot have $/ in the signature of a method that contains a .match statement, and I cannot have more than one .match inside the method because each .match will try to set the read-only $/ . This will be very awkward to program. Here is

问题 I have to sign a Soap message using java, but I can't use WSS4J, SAAJ, AXIS2 or CXF for classpath problems on my websphere server. I have to sign the body message of the SOAP call. I generate a XML with body inside body data correctly for the soap message and look like this: <SERVICE_DISPATCHER_REQUEST xmlns="http://inti.notariado.org/XML" xmlns:ns2="http://ancert.notariado.org/XML/CSN"><ns2:SERVICIO_CONSIGNACION_NOTARIAL><ns2:REQUEST><ns2:CABECERA><ns2:ID_COMUNICACION>2147483647</ns2:ID

问题 I have a signed PDF document. It was signed by using TCPDF. Now I want to verify it. This is my solution: Get content of signed pdf. Get original content and signature value base on /ByRange field. Get encrypted digest message from signature value. It's octet string at the end of signature value. Use Openssl_public_decrypt() function to decrypt the encrypted digest message with public key. Then we have a string which has a prefix ("3021300906052b0e03021a05000414"). This prefix denotes the

问题 I've a big problem. I work on a UWP Windows 10 application in C# and i would like to use OAuth 1. All is almost okay BUT the signature is wrong. However, I found the sample code on the Microsoft GitHub. Obviously, I have done some modifications... My code : private async Task GoCo() { String LifeInvaderUrl = "http://stage.api.lolilolz.be/v8/login"; string timeStamp = GetTimeStamp(); string nonce = GetNonce(); string consumerKey = "noob-stage"; string consumerSecret = "TOPSECRETxxXXxx"; string

问题 So I get different signatures for the same JWT. Header : { "alg": "HS512", "typ": "JWT" } Payload : { "sub": "1234567890", "name": "John Doe", "iat": 1516239022 } as a signing key I used " abc " The resulting JWT from jwt.io is the following: eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.sNgS2IRq0LCvUaIzg9dCBVvmY_9KnrXDEmKTii6U4APbRMeUkU084wf3h5v4baP2WeZOyGunCTEa9wxh25IW6w if I calculate the signature with python like this:
