How it works
Choose SHA-256, SHA-512, or CRC32, enter text, then select Generate hash. Copy the hexadecimal result when ready. Empty input is supported.
Useful notes
Text is encoded as UTF-8 without trimming whitespace or normalizing Unicode. Input is limited to 1 MiB of UTF-8 bytes. CRC32 uses the standard IEEE polynomial and is a checksum for accidental changes, not a cryptographic hash. This tool does not hash files or provide password storage.
