Hash Generator

Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes for text and files locally—batch mode included.

Ready

Hashes update locally as you type.

Hash is not encryption

Hashes are one-way fingerprints used for integrity checks, cache keys, and comparisons. They do not hide data and cannot be reversed into the original input. Use real cryptography when you need confidentiality.

About this tool

DevCove Hash Generator helps developers compute checksums and digests without uploading data. Hash UTF-8 text, drag and drop files, or process multiple lines in batch mode. MD5 and SHA outputs are generated locally with the Web Crypto API and a built-in MD5 implementation, so secrets, logs, and file contents stay on your device.

How to use this tool

Use this hash generator when you need quick checksums during development:

  1. Choose Text, File, or Batch depending on whether you are hashing a string, a downloaded artifact, or many values.
  2. Select the digest algorithms you need, such as SHA-256 for integrity checks or MD5 for legacy tooling.
  3. Paste UTF-8 text and copy individual hashes or the full result set.
  4. Drop a file to compute the same digests for binaries, logs, or config exports without uploading them.
  5. Use batch mode to hash one value per line for CSV prep, migration checks, or API payload comparisons.
  6. Remember that anyone with the same input can reproduce the same hash; do not treat hashes as secrecy.

Features

Built for everyday checksum and digest workflows:

  • MD5, SHA-1, SHA-256, SHA-384, and SHA-512 in one workspace.
  • UTF-8 text hashing with live updates.
  • Drag-and-drop file hashing up to 5 MB.
  • Batch line-by-line hashing with tab-separated copy output.
  • Optional uppercase hexadecimal output.
  • Per-algorithm copy buttons plus copy-all actions.
  • Clear warning that hashing is not encryption.
  • 100% browser-local processing; input is not sent to DevCove servers.
  • Useful alongside Base64, JWT, and password tools for debugging and verification tasks.

FAQ

Is MD5 still useful?

MD5 is weak for security-sensitive collision resistance, but developers still encounter it in legacy checksums, cache keys, and third-party tools. This generator supports it for inspection and migration work, not as a security guarantee.

What is the difference between hash and encryption?

A hash is a one-way digest of input data. Encryption is reversible when you hold the right key. Hashes help you compare or verify data; encryption protects confidentiality.

Are my files uploaded?

No. Text, batch lines, and files are hashed locally in your browser. DevCove does not receive the file contents.

Which SHA algorithm should I use?

SHA-256 is the most common default for integrity checks today. SHA-384 and SHA-512 are stronger and useful when a spec or platform requires them. SHA-1 is mostly legacy.

Why do I get the same hash every time?

Hashes are deterministic for the same bytes and algorithm. That is expected and useful for verifying downloads, configs, or API payloads.

Can I hash binary files?

Yes. File mode reads the raw bytes of the selected file and computes the selected digests locally.
