WebJun 21, 2024 · Just add a tip: Key length is dependent on the algorithm, such as for aes192, it's 24 bytes, or aes256, it's 32 bytes. You need to have a key length of 32 byte (256 bit). So if you change your key line to: let key = crypto.createHash ('sha256').update (String (secret)).digest ('base64').substr (0, 32); it will work.
