MD5 / SHA Hashing vs Encryption
Hashes are one-way digests for integrity — not a substitute for encryption.
A hash maps input to a fixed digest and is generally irreversible — used for integrity checks.
MD5/SHA1 are weak for security but still used for non-security checksums; prefer SHA256+ when it matters.
Hashing is not encryption: you cannot recover plaintext from a digest.
