Frequently Asked Questions About Hashing
What's the difference between MD5, SHA-1, SHA-256, and SHA-512?
MD5 (128-bit) and SHA-1 (160-bit) are legacy algorithms with known vulnerabilities. SHA-256 (256-bit) and SHA-512 (512-bit) are part of the SHA-2 family and are currently secure for cryptographic use. SHA-512 offers the highest security level.
Are MD5 and SHA-1 still safe to use?
MD5 and SHA-1 are not recommended for security-critical applications due to collision vulnerabilities. However, they're still useful for non-cryptographic purposes like checksums and data integrity verification where security isn't critical.
Is my data safe when using this hash generator?
Yes, absolutely. All hash calculations are performed locally in your browser. Your input data never leaves your device or gets transmitted to our servers, ensuring complete privacy and security.
Can I reverse a hash to get the original text?
No, hash functions are one-way operations. You cannot reverse a hash to get the original input. However, weak passwords or common phrases can sometimes be identified through rainbow table attacks or dictionary lookups.
Which hash algorithm should I choose for my use case?
For security applications (passwords, digital signatures), use SHA-256 or SHA-512. For simple checksums or non-security purposes, MD5 or SHA-1 may suffice. When in doubt, SHA-256 is the most widely adopted secure standard.
