Frequently Asked Questions
What is a cryptographic hash?
A cryptographic hash is a function that transforms any amount of data into a fixed-size string. It is used to verify data integrity, store passwords securely, and more.
Which algorithm should I use?
For modern security, use SHA-256 or SHA-512. MD5 and SHA-1 are considered insecure for cryptographic purposes but still useful for simple checksums.
Can a hash be reversed?
No. Hash functions are one-way. However, hashes of common texts can be found in 'rainbow tables'. For passwords, always use salt and dedicated algorithms like bcrypt.
