Generate cryptographic hash values using MD5, SHA-1, SHA-256, SHA-384, and SHA-512 algorithms. Hash functions are used for data integrity verification, password storage, and digital signatures.
Type or paste the text you want to hash into the input field. The hash will be calculated from the exact text entered, including any spaces or special characters.
Choose your hash algorithm:
The hash value appears instantly as a hexadecimal string. This value is unique to the input - any change produces a completely different hash.
Click copy to use the hash value in your applications or for verification purposes.
Support for MD5, SHA-1, SHA-256, SHA-384, and SHA-512.
Hash values computed in real-time as you type.
Results displayed in standard hexadecimal format.
Choose uppercase or lowercase hex output.
MD5 and SHA-1 are considered broken for security purposes - avoid for new projects.
Hashing is one-way - you cannot reverse a hash to get the original text.
Never store plain-text passwords - always hash them (preferably with bcrypt or Argon2).
A: For general purposes, use SHA-256. For passwords, use specialized algorithms like bcrypt or Argon2 (not available here). MD5 and SHA-1 should only be used for non-security purposes like checksums.
A: Hash functions are designed to be sensitive to input changes. Even adding a space or changing a letter produces a completely different hash. This is called the avalanche effect.
A: No, hashing is a one-way function. You cannot mathematically reverse a hash to get the original input. Rainbow tables can sometimes find matches for common strings, but this is not decryption.
A: A collision occurs when two different inputs produce the same hash. While theoretically possible, modern algorithms like SHA-256 make collisions practically impossible to find.
