- 01Generate SHA-1, SHA-256, SHA-384, or SHA-512 hashes of any text instantly — no server required.
- 02Output as hex (most common) or Base64 (compact, used in HTTP headers and token signatures).
- 03Hashing uses the browser's Web Crypto API — the same implementation behind HTTPS.
- 04SHA is not suitable for direct password storage; use bcrypt, scrypt, or Argon2 for passwords instead.
What SHA Hashing Is Used For
A cryptographic hash turns any input — a word, a document, a binary file — into a fixed-length fingerprint. The same input always produces the same hash, but changing even one character produces a completely different result. You cannot recover the original input from the hash alone. These properties make SHA hashes useful for verifying data integrity, building content-addressable storage, signing API requests, and generating checksums.
SHA-256 is the most widely deployed SHA variant today. It powers code-signing certificates, Git commit IDs, Bitcoin mining, and the HMAC signatures used by AWS, Stripe, and countless other APIs. SHA-512 offers a wider security margin on 64-bit hardware. SHA-1 is legacy and should be avoided for anything security-sensitive.
How to Generate a SHA Hash
- 01
Type or paste your text
Enter the text you want to hash into the input box. You can paste anything from a single word to a full document.
- 02
Choose the SHA variant
Select SHA-1, SHA-256, SHA-384, or SHA-512. For most modern uses SHA-256 is the right choice. Avoid SHA-1 for anything security-critical — use it only for compatibility with legacy systems.
- 03
Select hex or Base64 output
Hex is lowercase and the most common format (each byte becomes two hex digits). Base64 is more compact and is used in HTTP headers, HMAC signatures, and some token formats. Toggle at any time.
- 04
Copy the digest
Click the copy button to put the hash on your clipboard. Paste it wherever you need it — a verification check, an API signature, a config file.
When to Use Each SHA Variant
Pick the right variant for your context.
- 01SHA-256 — the standard choice for modern code signing, API HMAC signatures, and checksums.
- 02SHA-512 — provides extra security margin; preferred on 64-bit systems for high-value data.
- 03SHA-384 — less common; used in some TLS cipher suites and certificate authorities.
- 04SHA-1 — legacy only; supported here for verifying old checksums and compatibility with older systems.
- 05Hex output — default; best for human-readable digests and most API integrations.
- 06Base64 output — more compact; expected by HTTP headers and many HMAC token formats.
Your Input Never Leaves Your Browser
Hashing runs entirely in your browser using the SubtleCrypto API — the same Web Crypto standard used by HTTPS and browser-based TLS. Your text is processed locally and never transmitted to any server. This means you can hash sensitive strings, internal tokens, or proprietary content without any privacy concerns.

SHA Hash Generator FAQ
What is a SHA hash and how does it work?
SHA (Secure Hash Algorithm) is a cryptographic function that maps any input to a fixed-length digest. The same input always produces the same hash, but even a one-character change produces a completely different result. It is computationally infeasible to reverse a SHA hash back to its input.
Which SHA variant should I use?
Use SHA-256 for most modern applications — it is fast, widely supported, and secure. SHA-512 is a good choice when you want extra margin on 64-bit systems. Avoid SHA-1 for anything security-sensitive; it is broken for collision resistance.
Can I use SHA to store passwords?
No. SHA is too fast, making it vulnerable to brute-force attacks on common passwords. Use bcrypt, scrypt, or Argon2 for password hashing. SHA is appropriate for content integrity, file checksums, and API request signatures.
What is the difference between hex and Base64 output?
Hex uses 0–9 and a–f — every byte becomes two characters. Base64 encodes bytes into a–z, A–Z, 0–9, +, / — the output is shorter. Use hex when readability matters, Base64 when a compact representation is expected (HMAC headers, JWT signatures).
Is my text sent to a server?
No. Hashing uses the browser's SubtleCrypto API and happens entirely locally. Nothing is uploaded, logged, or stored.
Is the hash generator free?
Yes. All Handytool utilities are free with no sign-up and no usage limits.
