Frequently Asked Questions
What is a hash?▼
A hash is a fixed-size string generated from input data using a mathematical function. The same input always produces the same hash, but it's virtually impossible to reverse a hash back to the original data.
Which hash algorithm should I use?▼
SHA-256 is recommended for most purposes. MD5 and SHA-1 are considered cryptographically weak and should not be used for security. SHA-512 provides the highest security.
