Java 2 Interop:
Signatures generated using Java 2 java.security.Signature.sign() are in PKCS#1 v1.5 format, and for the same hash algorithm, content and RSA keys, are identical to signatures generated with .NET System.Security.Cryptography.RSAPKCS1SignatureFormatter.CreateSignature().
Certificate files for verification purposes can be easily exported from Java 2 keystores using:
byte keycert = keystore.getCertificate(
Cryptographic Message Syntax (CMS) and PKCS#7 specify a proposed standard for encapsulation of signatures along with certificates and other data. CMS/PKCS#7 messages are not currently supported natively in .NET Framework 1.0/1.1 nor in Java 2 v1.4. However the next release of .NET Framework will have some support for CMS/PKCS#7 messages. CMS/PKCS#7 is currently supported in CAPICOM 2 and the underlying CryptoAPI as well as 3rd party implementations for Java.
