Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text input.
How to use the hash generator
1
Enter your text
Type or paste text into the input area. The tool hashes its UTF-8 bytes exactly as entered, including accents, spaces, tabs and line breaks.
2
Generate the hashes
Select Generate to produce MD5, SHA-1, SHA-256 and SHA-512 together as lowercase hexadecimal. Processing happens entirely in your browser; your input is not sent anywhere.
3
Compare the outputs
MD5 produces 32 hex characters (128 bits), SHA-1 produces 40 (160 bits), SHA-256 produces 64 (256 bits), and SHA-512 produces 128 (512 bits). When comparing results, check that the input matches exactly, including any trailing newline.
4
Clear the input
Use Clear to reset the widget before entering another text. This tool accepts text only, with no file upload, secret-key HMAC or salt option.
Use hello without a trailing newline to compare the four algorithms. The MD5 examples show how capitalization, a newline and empty input affect the result.
Enter your text and select Generate to get its MD5, SHA-1, SHA-256 and SHA-512 hashes at once. A hash is a fixed-length digest of the input, so the same text always produces the same result for a given algorithm. This text-to-hash converter processes UTF-8 bytes locally in your browser.
Can a hash decoder reverse a hash?
No, a hash cannot be decoded or decrypted to recover the original text. A hash function is one-way and has no decryption key. Sites offering hash decode usually search precomputed tables or guess candidate inputs until a hash matches, which can work for common passwords but is not a way to reverse long random input.
Is MD5 safe, and how does MD5 compare with SHA-256?
MD5 is unsuitable for security decisions; SHA-256 is a general-purpose choice for integrity checks and digital signatures. MD5 and SHA-1 have known collision attacks, so avoid both for signatures and certificates. An MD5 hash generator remains useful for non-adversarial checksums, cache keys and de-duplication. SHA-512 is another SHA-2 option, with a 512-bit output.
Can I use a SHA256 hash generator to store passwords?
No, a plain SHA-256 hash is not suitable for password storage. MD5, SHA-1, SHA-256 and SHA-512 are fast, allowing attackers to test password guesses quickly. Use a slow, salted password hashing scheme such as bcrypt, scrypt or Argon2 instead. This widget does not offer password hashing or a salt option.
Why does my terminal produce a different hash?
A trailing newline can make your terminal hash different from the hash of the text alone. The command echo "hello" | md5sum includes a newline and produces b1946ac92492d2347c6235b4d2611184. Use printf or echo -n to hash hello alone, which produces 5d41402abc4b2a76b9719d911017c592. Spaces, tabs and other input differences also change the result.
Is this a random hash generator?
No, this hash generator is deterministic and does not create random input. Entering the same text again gives the same four hashes; changing the text changes the results. If you need a random password or a random identifier, use a password generator or UUID generator respectively.
