Frequently Asked Questions
What is a hash algorithm and how does it work?
A hash algorithm is a one-way function that converts input data of any size into a fixed-length output called a hash or digest. Even a small change in input produces a completely different hash. Hash functions are deterministic — the same input always produces the same output.
What is the difference between MD5, SHA, and CRC algorithms?
MD5 produces a 128-bit hash, SHA family offers various bit lengths (SHA-1: 160-bit, SHA-256: 256-bit, SHA-512: 512-bit), and CRC algorithms generate short checksums used for error detection rather than cryptographic security.
Which hash algorithm is the most secure?
SHA-256 and SHA-512 are widely considered cryptographically secure for most applications. For the highest security, SHA-3 (Keccak) and SHA-512 are recommended. MD5 and SHA-1 are considered broken and should not be used for security-sensitive applications.
Can a hash be reversed back to the original text?
No. Hash functions are designed to be one-way — you cannot reverse a hash back to the original input. However, attackers can use rainbow tables or brute force to find matching inputs. For password storage, use algorithms like bcrypt or argon2 instead.
Why does the same text produce the same hash every time?
Hash functions are deterministic by design. The same input will always produce the same hash output. This property makes hashes useful for verifying data integrity, comparing files, and storing passwords (when combined with salting).
