It uses a hash algorithm like SHA256 to create a Message Authentication Code (a MAC) that can be used to verify the integrity of the message, and because it's based on a shared secret key, verify the identity of the sender. There's no encryption in there at all
WebSep 24, 2024 · To generate a signature, sign the string with your private key using a ES256 algorithm (also known as ECDSA using P-256 curve and SHA-256 hash algorithm). The signature must be Base64 URL-encoded. I don't need to decrypt anything, I just need to sign the string and add it to the end of my request URL. So I don't think I need anything … WebOct 6, 2024 · I will show you exactly how this works with Flutter.
