WebSHA-1 (and all other hashing algorithms) return binary data. That means that (in Java) they produce a byte[].That byte array does not represent any specific characters, which means you can't simply turn it into a String like you did.. If you need a String, then you have to format that byte[] in a way that can be represented as a String (otherwise, just keep the …

WebMar 23, 2013 · 5. FNV-1 is rumoured to be a good hash function for strings. For long strings (longer than, say, about 200 characters), you can get good performance out of the MD4 hash function. As a cryptographic function, it was broken about 15 years ago, but for non cryptographic purposes, it is still very good, and surprisingly fast. WebJul 9, 2024 · key (string): if you want to use HMAC to key-hash a string, provide it as second argument. raw (boolean): a boolean that determines whether the hash should be raw or hex encoded (false by default). MD5 hash (hex-encoded) You can easily create the MD5 hash of any given string providing it as first argument: tim green city of lenexa
