Text Processing
Compute MD5, SHA-1, SHA-256, SHA-512, and CRC-32 hashes of any text in one shot. Get both hex and Base64 digests over the UTF-8 encoding.
Details
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.
Execution
Fill in the form, run the tool, and review the result in one place.

Tool usage guide
Text Hash Generator computes a selected MD5, SHA-1, SHA-256, SHA-512, or CRC-32 digest from UTF-8 text and displays the result in lowercase hexadecimal, with optional Base64 output.
Background
A developer needs a stable fingerprint for the text value used in a cache key.
Problem
The digest must be generated consistently and available in a standard hexadecimal format.
How to use
Enter `hello world`, choose SHA-256, and select Hex + Base64.
Algorithm: SHA-256; Output formats: Hex + Base64Outcome
The hexadecimal SHA-256 digest is `b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9`.
Background
A legacy system requires an MD5 value to compare a text-based cache entry.
Problem
The required checksum needs to be generated quickly in the expected hexadecimal format.
How to use
Enter `hello world`, choose MD5, and select Hex + Base64.
Algorithm: MD5; Output formats: Hex + Base64It supports MD5, SHA-1, SHA-256, SHA-512, and CRC-32.
The digest is calculated from the text's UTF-8 byte encoding.
Yes. Select Hex + Base64 to receive both formats.
SHA-256 is the recommended modern option. MD5 and SHA-1 are legacy algorithms, while CRC-32 is not cryptographic.
CRC-32 provides a fast, non-cryptographic checksum for detecting accidental changes.
Outcome
The hexadecimal MD5 digest is `5eb63bbbe01eeed093cb22bb8f5acdc3`.
