Web1. if I cerate a hash using CryptCreateHash, then sign it using CryptSignMessage, it will be a valid PKCS#7 format signature. 2. To verify it, i need to obtaint the certificate using CryptVerifySignature, then I need to get a signed hash from that signature (how??), create a hash from the text I need to check for WebApr 17, 2011 · My first certificate works well, but the others don't - CryptSignMessage fails with 0xb7 error for no obvious reason. All certificates are valid, for sha256 with 2048 bit key length. My OS is Vista, so I suppose it can handle sha256. I've an iKey 4000 token with installed dll driver - everything suggests it should work.

WebApr 22, 2024 · SHA-256, which stands for secure hash algorithm 256, is a cryptographic hashing algorithm (or function) that’s used for message, file, and data integrity verification. It’s part of the SHA-2 family of hash functions and uses a 256-bit key to take a piece of data and convert it into a new, unrecognizable data string of a fixed length.
