SHA Hash Generator
Create a hexadecimal digest from UTF-8 text using a standard browser cryptography implementation.
What is this tool?
A cryptographic hash maps input to a fixed-length digest. The same input and algorithm always produce the same result, while even a small input change creates a very different digest.
How to use
- Enter the exact text you want to hash.
- Select a SHA algorithm.
- Generate the digest.
- Copy the hexadecimal result.
Example
The SHA-256 digest of hello begins with 2cf24dba5f….
FAQ
Can a hash be reversed?
A cryptographic hash is designed to be one-way. Weak inputs can still be guessed using dictionaries.
Should I use SHA-1?
SHA-1 remains useful for compatibility checks but is collision-broken. Prefer SHA-256 or stronger for new security-sensitive work.
Can this hash passwords?
Do not store passwords with raw SHA hashes. Use a dedicated password-hashing function such as Argon2, scrypt or bcrypt with salts.
