This tool hashes your input with the MD5 algorithm and shows the 32-character hexadecimal result. Use it to create quick fingerprints, compare checksums, or learn how MD5 works.
How it works
Type or paste any string into the field. The MD5 value updates as you type.
MD5 processes your text as UTF-8 bytes and produces a fixed 128-bit hash, shown here as 32 hexadecimal characters (0–9, a–f).
What is MD5?
MD5 (Message-Digest Algorithm 5) is a cryptographic hash function. It maps data of any size to a 128-bit value. The same input always produces the same hash, but the hash cannot be reversed to recover the original text.
Security note
MD5 is not considered safe for cryptography today. It is vulnerable to collision attacks and must not be used for passwords, TLS, or signatures. Prefer SHA-256 or SHA-3 for security-sensitive work. This page is for checksums, legacy workflows, and learning.
Common questions
- Is this MD5 generator free?
- Yes. There is no limit and no signup. Hashing runs in your browser.
- Do you store my text?
- No. Your input is processed locally in the page; nothing is sent to a server to compute the hash.
- Why is the MD5 output 32 characters?
- MD5 outputs 128 bits. Written in hexadecimal, that is 32 digits.
- Should I use MD5 for passwords?
- No. Use a modern password hash such as Argon2, bcrypt, or scrypt with a unique salt per user.
