# Text Hash Generator 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. > Canonical page: https://elysiatools.com/en/tools/text-hash-generator - **Category:** Text Processing - **Keywords:** text hash, md5, sha1, sha-256, sha-512, crc32, checksum, digest, sha256, fingerprint ## Overview 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. ## Inputs - **Text to hash** (textarea): Type or paste any text… - **Output formats** (select) - **Algorithms** (select) ## When to use - Create a SHA-256 fingerprint for text used in a cache key or content-addressable identifier. - Compare text checksums when verifying data integrity or transfers. - Generate legacy MD5 or SHA-1 values for systems that still require them. ## How it works - Enter or paste the text to hash. - Choose an algorithm: MD5, SHA-1, SHA-256, SHA-512, or CRC-32. - Select Hex only or Hex + Base64 output. - Review and copy the generated digest. ## Use cases - Generate cache keys and stable text fingerprints with SHA-256 or another selected algorithm. - Create checksums for comparing text before and after transfer. - Teach how identical UTF-8 input produces fixed-length hexadecimal and Base64 digests. ## Frequently asked questions ### Which algorithms does the tool support? It supports MD5, SHA-1, SHA-256, SHA-512, and CRC-32. ### What encoding is used for the input text? The digest is calculated from the text's UTF-8 byte encoding. ### Can I get the hash in Base64? Yes. Select Hex + Base64 to receive both formats. ### Which algorithm is recommended for new uses? SHA-256 is the recommended modern option. MD5 and SHA-1 are legacy algorithms, while CRC-32 is not cryptographic. ### What is CRC-32 used for? CRC-32 provides a fast, non-cryptographic checksum for detecting accidental changes. ## Related tools - [Hash Algorithm Comparator](https://elysiatools.com/en/tools/hash-algorithm-comparator): Hash the same input with MD5, SHA-1, SHA-256, SHA-512, BLAKE2b, and BLAKE3 at the same time and compare them side by side: output length, hex/Base64 digest, security status (broken / modern), and a relative speed benchmark. Great for teaching, choosing a hashing algorithm, or sanity-checking checksums. - [Hash Generator](https://elysiatools.com/en/tools/hash-generator): Generate hash values (MD5, SHA1, SHA256, SHA512) - [Audio Hash](https://elysiatools.com/en/tools/audio-hash): Generate cryptographic hashes (checksums) for audio files - [PKCE Code Verifier & Challenge Generator](https://elysiatools.com/en/tools/pkce-code-verifier-generator): Generate, validate and verify OAuth2 / OIDC PKCE (RFC 7636) code_verifier and S256 code_challenge pairs. Three modes: (1) generate a fresh verifier + challenge from cryptographically secure random bytes at 256/384/512/768-bit entropy, (2) audit a verifier you already have against the RFC — length (43–128), charset \[A-Za-z0-9-._~\] and ≥256-bit entropy, and (3) verify a verifier/challenge pair by recomputing BASE64URL(SHA256(verifier)). Optionally build the full authorization-request URL and token-exchange body. Complements the generic nonce-generator (which only emits a verifier+challenge pair) with RFC-compliance auditing and pair verification. - [CRC32 Checksum](https://elysiatools.com/en/tools/crc32-checksum): Compute the CRC32 checksum (IEEE 802.3 polynomial) of any text or raw bytes.
