Frequently Asked Questions
What is a hash?
A hash is a fixed-size string generated from input data using a mathematical function, commonly used for data integrity verification and password storage.
Can I reverse a hash to get the original data?
No. Cryptographic hash functions are one-way and cannot be reversed to recover the original input data.
Which hash algorithm should I use?
SHA-256 is recommended for most purposes. MD5 and SHA-1 are considered cryptographically weak and should only be used for non-security checksums.
