Frequently Asked Questions
- What is the difference between MD5, SHA-1, SHA-256, and SHA-512?
- They differ in speed and security. MD5 (128-bit) and SHA-1 (160-bit) are fast but cryptographically broken — avoid them for security purposes. SHA-256 (256-bit) and SHA-512 (512-bit) are secure and recommended. Use SHA-256 for general checksums and SHA-512 for high-security applications.
- Can I reverse a hash to get the original text?
- No — hashing is a one-way function by design. You cannot mathematically reverse a hash. However, common short strings (passwords, known words) may be found in precomputed rainbow table databases. This is why passwords should always use salted hashing.
- How do I verify file integrity with a hash?
- Hash the file before transfer or download, then hash it again after receiving it. If both hashes match exactly, the file is identical and has not been corrupted or tampered with. Software download pages often publish SHA-256 checksums for this purpose.
- Which hash algorithm should I use for my project?
- Use SHA-256 for general checksum verification and most development use cases. Use SHA-512 when you need maximum security margin. Only use MD5 or SHA-1 when required by a legacy system — never for any new security-related code.
