What is a hash generator?

A hash generator is a tool that creates a fixed-size cryptographic hash from input data. It uses algorithms like MD5, SHA-256, or SHA-512 to convert text or files into unique hash values for security, verification, and data integrity purposes.

Is MD5 secure for password hashing?

No, MD5 is not secure for password hashing. It is vulnerable to collision attacks and rainbow table attacks. For password hashing, use modern algorithms like bcrypt, scrypt, or Argon2. MD5 can still be used for checksums and non-security purposes.

What is the difference between SHA-256 and SHA-512?

SHA-256 produces a 256-bit (32-byte) hash, while SHA-512 produces a 512-bit (64-byte) hash. SHA-512 is more secure but slower. SHA-256 is faster and sufficient for most use cases. Both are part of the SHA-2 family and are cryptographically secure.

Can I use this hash generator for files?

Yes! You can upload text files (.txt, .json, .xml, .csv) and generate hashes for their contents. This is useful for verifying file integrity and creating checksums.
