Compute the MD5 digest of a URL / text (128 bit, 32 hex chars)
Compute MD5 / SHA digests of text to verify integrity.
MD5, SHA-1, SHA-256, SHA-512 and other common algorithms.
Verify whether a file or text has been tampered with.
Hashing is one-way and cannot recover the original from the digest; for security-sensitive checks, avoid MD5 / SHA-1, which are known to be broken.
