Can the ByteKiln Hash Generator hash files?
Yes. Switch to the File tab and drop any file onto the upload zone. SHA-1, SHA-256, SHA-384, and SHA-512 are computed in-browser using the SubtleCrypto API. MD5 is available for text input only.

How the Hash Generator Works
The ByteKiln Hash Generator computes MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text or files entirely in your browser. File hashes use the Web Crypto API — no data is uploaded.
Hashing text
Type or paste any text into the input and all five algorithms are computed simultaneously. Results are displayed as lowercase hex strings and update in real time as you type.
Hashing files
Switch to the File tab and drop any file. SHA-1 through SHA-512 are computed from the raw file bytes using SubtleCrypto.digest(). MD5 is text-only since it is not available in the browser's native Crypto API.
Choosing the right algorithm
Use SHA-256 for checksums, data integrity, and modern security use cases. SHA-512 offers higher collision resistance. MD5 and SHA-1 are included for legacy checksum verification only — they are cryptographically broken and should not be used for security.
FAQ
Short answers for the things developers usually ask before trusting a tool.
Should I use MD5 or SHA-1 for password hashing or security?
No. MD5 and SHA-1 are cryptographically broken and unsuitable for passwords or digital signatures. They are included for checksum verification and legacy compatibility workflows only. Use bcrypt, argon2, or SHA-256 for security purposes.
Is my data uploaded when I generate a hash?
No. The ByteKiln Hash Generator processes all input locally in your browser using the Web Crypto API. Your text or files are never transmitted to any server.
What is a hash used for in practice?
Hashes are used to verify file integrity (checksums), securely store passwords (with a proper algorithm), generate unique identifiers, detect data tampering, and create digital signatures. SHA-256 is the most widely used today.
Can I hash the same input and always get the same output?
Yes. Hash functions are deterministic — the same input always produces the same hash output. This property makes hashes useful for verification: if two hashes match, the inputs are identical.
