About hashes

MD5 and SHA-1 are cryptographically broken, fine for file checksums, but never use them for passwords or signatures.
SHA-256 and SHA-512 are still considered secure for general hashing needs.
For password storage, use bcrypt, argon2 or scrypt, not plain SHA.
All hashing happens locally via the Web Crypto API and a small MD5 library; your text never leaves the browser.
