A hash is a checksum, not encryption. The original text normally cannot be meaningfully recovered from a hash value.

Notes

SHA-256 is a good default for many checksums and integrity checks.
SHA-384 and SHA-512 produce longer hash values.
SHA-1 is outdated and should only be used for compatibility or comparing old hash values.
Simple hashes are not enough for passwords. Password storage needs specialized password hashing methods.
