What text encoding is used to compute hashes?

All digests are computed over the UTF-8 byte encoding of your input text.

Which algorithms are supported by this tool?

It supports MD5, SHA-1, SHA-256, SHA-512, and CRC-32.

What output formats are available for the digests?

You can output digests as lowercase hexadecimal strings or both hexadecimal and Base64.

Is CRC-32 suitable for cryptographic security?

No, CRC-32 is a non-cryptographic checksum intended for error-checking, not security.

Can I hash multiline strings or special characters?

Yes, any multiline text, symbols, and Unicode characters are accepted and encoded via UTF-8.

What this tool helps you do

A one-stop text hashing utility. Paste text and instantly get all five common digests: MD5 (128-bit, legacy), SHA-1 (160-bit, deprecated for security), SHA-256 (the recommended modern hash), SHA-512, and CRC-32 (a fast non-cryptographic checksum). Hashes are computed over the UTF-8 byte encoding of the input, and each is shown in both lowercase hex and Base64. Useful for generating cache keys, file/integrity checksums, content-addressable IDs, dedup keys, verifying data transfer, and teaching how the same input yields fixed-length fingerprints. Copy buttons work even inside the sandboxed preview via an execCommand fallback.
