About Cryptographic Hashes

  • MD5: 128-bit hash (32 hex characters) - Fast but not cryptographically secure
  • SHA-1: 160-bit hash (40 hex characters) - Deprecated for security
  • SHA-256: 256-bit hash (64 hex characters) - Secure and widely used
  • SHA-384: 384-bit hash (96 hex characters) - More secure variant
  • SHA-512: 512-bit hash (128 hex characters) - Maximum security

Use cases: File integrity verification, password hashing, digital signatures, and data deduplication.

How to Use

  1. 1Choose between 'Text' or 'File' mode depending on what you want to hash
  2. 2For text: enter or paste your content in the text area
  3. 3For files: click 'Choose File' and select your file from your computer
  4. 4Select one or more hash algorithms (MD5, SHA-1, SHA-256, SHA-384, SHA-512)
  5. 5Click 'Generate Hashes' to compute the hash values
  6. 6Copy individual hashes using the copy button next to each result

Hash Examples

Text: 'Hello World'

MD5: b10a8db164e0754105b7a99be72e3fe5

MD5 hash of the text 'Hello World'

SHA-256 Example

SHA-256: a591a6d40bf420404a011733cfb7b190d62c65bf0bcda32b57b277d9ad9f146e

SHA-256 is recommended for most security applications

File Integrity

Compare hash before and after file transfer to verify integrity

If hashes match, the file hasn't been modified or corrupted

Hash Generator Best Practices

  • Use SHA-256 or higher for cryptographic security - MD5 and SHA-1 are outdated
  • Hash values are deterministic: same input always produces the same hash
  • Even a tiny change in input produces a completely different hash
  • Hashing is one-way: you cannot reverse a hash to get the original data
  • Use hashes to verify file integrity after downloads or transfers
  • Store multiple hash types (SHA-256, SHA-512) for critical file verification
  • Never use MD5 or SHA-1 for passwords or security-critical applications
