Step 1
Paste the text you want to hash into the input field.
Hash Generator Online
Use NewTools to generate SHA hashes directly in your browser. Creates SHA-1, SHA-256, SHA-384, or SHA-512 hashes with Web Crypto.
Browser-Native Hashing. Quickly create hashes from text using standard SHA algorithms, completely client-side.

Features
SHA Algorithm Family: Supports standard SHA-1, SHA-256, SHA-384, and SHA-512 hash algorithms.
Hexadecimal Output: Calculates and outputs the resulting digest in standard hexadecimal string format.
Web Crypto API: Uses native browser capabilities (crypto.subtle.digest) for reliable hashing.
Local Processing: Processes your text entirely offline. No data is transmitted to an external API.
How It Works

Step 2
Select your desired algorithm (e.g., SHA-256).
3
Step 3
Copy the generated hexadecimal digest.
Common Use Cases
Data Integrity Checking
Verify that text strings match a known expected SHA-256 hash value.
Webhooks Signatures
Generate expected signature hashes during developer testing.
API Token Hashing
One-way hash raw tokens for secure storage references.
Tips & Best Practices
Tip 1
SHA-256 is the modern recommended standard for general data hashing.
Tip 2
The output is strictly hexadecimal. Base64 digest output is not supported.
Hash Generator
Fast Local Execution
Because this tool relies on crypto.subtle.digest, sensitive text never leaves your device. It offers robust utility for local hashing tasks.
Frequently Asked Questions
Does this tool support MD5 or bcrypt?
No. We exclusively support the modern SHA algorithms natively available in the Web Crypto API.
Can I hash files?
This specific tool is designed for text string input only.
Is hashing the same as encryption?
No. Hashing is a one-way mathematical function used to generate a fixed-size fingerprint of data. Unlike encryption, a hash cannot be decrypted back into the original text.
