Question 1

Is this hash generator secure?

Accepted Answer

Yes. All hashing uses the browser's native Web Crypto API (for SHA) and runs entirely locally. No data is transmitted.

Question 2

Which hash algorithm should I use?

Accepted Answer

SHA-256 is recommended for most use cases. Use SHA-512 for extra security. Avoid MD5 and SHA-1 for security-critical applications.

Question 3

Can I reverse a hash?

Accepted Answer

No. Cryptographic hash functions are one-way. You cannot recover the original input from a hash output.

Question 4

Is MD5 still safe to use?

Accepted Answer

MD5 is no longer considered secure for cryptographic purposes due to known collision vulnerabilities. Use SHA-256 or SHA-512 for security-sensitive applications.

Question 5

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

Accepted Answer

SHA-256 produces a 256-bit hash, while SHA-512 produces a 512-bit hash. SHA-512 can be faster on 64-bit processors.
