Which hash algorithm should I use?

For security applications, use SHA-256 or higher. MD5 and SHA-1 are cryptographically broken and should only be used for checksums, not security.

Can I hash files with this tool?

This tool currently supports text input. For file hashing, you can copy and paste file contents or use command-line tools for binary files.

Are the generated hashes secure?

The hashes are generated using standard algorithms. SHA-256 and higher are considered cryptographically secure, while MD5 and SHA-1 should not be used for security purposes.

Can I reverse a hash to get the original text?

No, cryptographic hashes are one-way functions. You cannot reverse a hash to get the original input. This is why they are used for password storage.

Select Hash Algorithms

MD5

Fast but cryptographically broken - use for checksums only

SHA-1

Legacy algorithm - not recommended for security

SHA-256

Secure and widely used - recommended for most cases

SHA-384

Higher security variant of SHA-2

SHA-512

Highest security SHA-2 variant

Algorithm Information

MD5

128-bit hash, fast but cryptographically broken. Use only for checksums.

SHA-1

160-bit hash, deprecated for security applications but still used in Git.

SHA-256

256-bit hash, secure and widely recommended for most applications.

SHA-384/512

Higher security variants with longer output lengths.

Common Use Cases

• File Verification: Verify file integrity after transfer
• Password Storage: Hash passwords before database storage
• Digital Signatures: Create unique identifiers for data
• Blockchain: Proof-of-work and transaction verification
• Data Deduplication: Identify duplicate content
• API Security: Generate request signatures

Security Notes

• Never use MD5 or SHA-1 for security purposes
• Add salt when hashing passwords
• Use SHA-256 or higher for cryptographic applications
• Hashes are one-way - cannot be reversed
• Different inputs should produce different outputs
• Same input always produces the same hash
