Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from any text input. Useful for checksums, data integrity, and security.
Enter text above...Enter text above...Enter text above...Enter text above...Enter text above...Enter text above...A cryptographic hash function takes input of any size and produces a fixed-length output (digest) that acts as a unique fingerprint. The same input always yields the same hash, but even changing a single character produces a completely different output this is called the avalanche effect.
Change a single bit in the input and roughly 50% of the output bits flip. "Hello" and "hello" produce completely different SHA-256 hashes with no discernible pattern. This property is what makes hash functions useful for integrity verification any tampering is immediately detectable.

Understand the SHA-256 hashing that underpins Bitcoin's proof-of-work.
A hash function takes input data of any size and produces a fixed-size output (hash/digest). The same input always produces the same hash, but it's practically impossible to reverse the hash back to the original input.
MD5 produces a 128-bit (32-character) hash and is considered cryptographically broken - do not use it for security. SHA-256 produces a 256-bit (64-character) hash and is currently secure. Use SHA-256 for checksums and integrity verification.
No. Hashing is a one-way function - you cannot reverse a hash to get the original data. Encryption is two-way - encrypted data can be decrypted with the correct key. Use hashing for checksums and password storage, encryption for data confidentiality.
