How to compute MD5/SHA digests for a text input

1. Enter the text

   "Text" is the string to hash. UTF-8 bytes are what's hashed — accented characters and emoji count as their multi-byte form, so `é` is 2 bytes, not 1.

2. Choose the algorithm

   "Algorithm" picks from `md5`, `sha1`, `sha256`, `sha384`, `sha512`. SHA-256 and above are recommended for anything new; MD5 and SHA-1 are kept for compatibility with legacy systems but are NOT secure against collisions.

3. Press Run

   Result returns a single `digest` field as lowercase hex. Lengths: MD5 32 chars, SHA-1 40, SHA-256 64, SHA-384 96, SHA-512 128.

4. What hashes are not

   Hashes are NOT encryption — there's no decode. They're also NOT a good password store on their own; use bcrypt-generator for password hashing because plain SHA is too fast and rainbow-tabled.
