Frequently Asked Questions
What is a cryptographic hash function?
A cryptographic hash function is a mathematical algorithm that maps data of arbitrary size (text or files) to a bit array of a fixed size (the hash or checksum). It is a one-way function, meaning it is computationally infeasible to invert (recover the original text from the hash value).
What are the differences between MD5, SHA-1, and SHA-256?
The main differences lie in security and bit-length. MD5 (128-bit) and SHA-1 (160-bit) are older algorithms that are now considered cryptographically broken due to collision vulnerabilities. SHA-256 (256-bit) and SHA-512 (512-bit) belong to the modern SHA-2 family and are highly secure, widely used in blockchain, SSL certificates, and file verification.
What is a hash collision?
A hash collision occurs when two different inputs produce the exact same output hash. Because the number of possible inputs is infinite and the output size is fixed, collisions must mathematically exist. However, for modern hashes like SHA-256, the likelihood of finding one is virtually zero.
Can I decode a hash back to text?
No, hashes are designed to be one-way functions. You cannot reverse a SHA-256 or MD5 hash directly. The only way to find the original text is by guessing the input and comparing the resulting hash (brute-forcing or checking pre-computed databases called 'rainbow tables').
