Can a hash be decrypted back to text?

No. Cryptographic hashes are one-way; they cannot be reversed.

Is it safe to hash my password here?

Yes. The tool runs in your browser so your password is not transmitted to or stored by our servers.

Which algorithm is most secure?

SHA-256 and SHA-512 are the current standard for cryptographic hashing.

Can I get the hash in Base64 instead of hex?

Yes. Use the Hex/Base64 toggle to output hashes in Base64 format, useful for some APIs or storage.

哈希生成

The Hash Generator produces one-way cryptographic hashes from any string using MD5, SHA-1, SHA-256, and SHA-512. Because hashes are used for passwords and checksums, the tool uses the Web Crypto API in your browser so your input is not sent to our servers for hashing.
