verify

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 have this method in my Codeigniter (version 3.0) login module. It works fine but is this safe? Is any better solution to check login and password using PHP password_verify? (PHP 5.6, MySQL 5.0). $user = $this->input->post('username'); $password = $this->input->post('password'); $myquery = $this->db->query("SELECT * FROM users WHERE user = '$user'"); $row = $myquery->row(); if (isset($row)) { //Using hashed password - PASSWORD_BCRYPT method - from database $hash = $row->password; if

问题 How can I get a signing chain from a CMSSignedData (BouncyCastle) to verify it with the signing chain store? Certificate[] storeCertChain = store.getCertificateChain(alias) Isn't there a command or something like this I can get the signing chain of the data? Or get the certificate from it and there from the signing chain? 回答1: The chain of the certificate used to sign might be in the CMSSignedData , but it's not mandatory. According to RFC 3852, a CMS SignedData has the following structure

问题 When I used openssl APIs to validate server certificate (self signed), I got following error : error 19 at 1 depth lookup:self signed certificate in certificate chain As per openssl documentation, this error (19) is "X509_V_ERR_SELF_SIGNED_CERT_IN_CHAIN: self signed certificate in certificate chain - the certificate chain could be built up using the untrusted certificates but the root could not be found locally." Why this error occurs ? Any problems with my server certificate ? 回答1: You have

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 try to use X509Certificate2.Verify() function to check if a certificate chain is valid. The Verify function returns false and the ChainElementStatus returns "RevocationStatusUnknown". Is there a way to use the Verify function without the check of the RevocationStatus? The RevocationStatus can't be checked without internet connection? Is there a other function to check the chain and certificates wihtout the RevocationStatus? A dirty solution, is to check if the RevocationStatus is the only

问题 I have to place a file in remote SFTP server before that I have to sign the file with the private key and they will verify it with the public key. I am getting "PGP Signature verification failed" error from the response file. So I tried to verify the sign from JAVA. Still, I am getting false value from the signature verify method. Any help would be appreciated. Here's a code that I've put together. public class SignAndVerify { static final KeyFingerPrintCalculator FP_CALC = new

问题 for a unit tests i am trying to verify if there is a way to verify a method call inside a method with mockito verify? An example would be: public delete(param) { VideoService.deleteVideo(param); << i want to verify the call of this method return etc.. } I can check if delete is called with : verify(mock,times(1)).delete(param); Is there also like a way to check the inside method like: verify(mock,times(1)).delete(param).VideoService.deleteVideo(param); 回答1: You can use a spy. public class
