问题 I have a file which has been encrypted by des.exe. A file can be encrypted and decrypted using the following commands: des -E -k "foo" sample.txt sample.txt.enc des -D -k "foo" sample.txt.enc sample.txt.dec I have attempted to decrypt using the following: public byte[] Decrypt(FileInfo file, string key) { byte[] keyAsBytes = LibDesPasswordConvertor.PasswordToKey(key); byte[] initializationVector = keyAsBytes; var cryptoProvider = new DESCryptoServiceProvider(); cryptoProvider.Mode =

问题 I am getting above mentioned error during a hybrid cryptography implementation. as per https://en.wikipedia.org/wiki/Hybrid_cryptosystem I am just stucked at the last step My code is private void button1_Click(object sender, EventArgs e) { try { CspParameters cspParams = new CspParameters { ProviderType = 1 }; RSACryptoServiceProvider rsaProvider = new RSACryptoServiceProvider(2048, cspParams); string publicKey =lblPublicKey.Text = Convert.ToBase64String(rsaProvider.ExportCspBlob(false));

问题 SigningCredentials on .NET Core is different from .NET 4.0 回答1: The equivalent code in .NET Core would be: var key = Encoding.UTF8.GetBytes(accessKey); var signingKey = new SymmetricSecurityKey(key); var signingCredentials = new SigningCredentials(signingKey, SecurityAlgorithms.HmacSha256); The class names have changed a little, but everything should work the same. Make sure you are using the latest package versions. 来源： https://stackoverflow.com/questions/38089523/signingcredentials-on-net

问题 Is there any way to pass extra authenticated attributes for a PKCS#7 signed message using openssl? I'm stuck with the command-line. I'm currently using : openssl smime -sign -outform DER -md sha1 -binary -signer my.crt -inkey my.key I did not find any releveant option in openssl cli help. More info : I'm currently trying to build a SCEP (http://tools.ietf.org/pdf/draft-nourse-scep-23.pdf) server in NodeJS. SCEP spec requires to build PKCS#7 signed pkiMessages , The SignerInfo MUST contain a

问题 Is Bouncy Castle API Thread Safe ? Especially, org.bouncycastle.crypto.paddings.PaddedBufferedBlockCipher org.bouncycastle.crypto.paddings.PKCS7Padding org.bouncycastle.crypto.engines.AESFastEngine org.bouncycastle.crypto.modes.CBCBlockCipher I am planning to write a singleton Spring bean for basic level cryptography support in my app. Since it is a web application, there are greater chances of multiple threads accessing this component at a time. So tread safety is essential here. Please let
