  2. The CRC32 and Adler-32 checksums (in hex) are shown automatically.

FAQ

What's the difference between CRC32 and Adler-32?

Both are checksum algorithms used for error detection. CRC32 is commonly used in ZIP files, while Adler-32 (used in zlib compression) is faster to compute but offers somewhat weaker error detection.

Can this checksum an actual file?

No โ€” this tool only checksums text input. To hash a file, try our Hash Generator.

Can I use this as a security hash?

No. CRC32 and Adler-32 are error-detection checksums, not cryptographically secure hash functions. Use something like SHA-256 for security purposes.
