Core Features
- Generate MD5, SHA-1 and SHA-256 hashes.
- Explain hashing versus encryption.
- Support checksum and comparison workflows.
- Warn about password storage misuse.
How to Use
- Paste the text you need to hash.
- Choose the hash algorithm required by your workflow.
- Copy the digest and compare it with the expected value.
- Avoid using weak hashes for security-sensitive storage.
Common Errors
- Expecting a hash to be decrypted.
- Using MD5 for password storage.
- Comparing hashes generated from text with different encodings.
- Forgetting that whitespace changes the digest.
Real Developer Use Cases
- Checking whether two strings are identical without exposing the original text.
- Creating examples for API signing documentation.
- Verifying small checksum workflows in the browser.
Technical Explanation
A hash function turns input into a fixed-length digest. It is useful for comparison and integrity checks, but it is not encryption and cannot be reversed. Algorithm choice matters: MD5 and SHA-1 are not appropriate for modern security-sensitive uses, while SHA-256 remains common for checksums and documentation examples.
