MD5 Hash Generator
Type text and get MD5 instantly, with length and letter-case options.
Note: MD5 is a hash function, not reversible encryption.
- Type or paste text to calculate MD5.
- The "MD5 Hash Result" area updates in real time.
- Switch output length between "32 chars (Full)" and "16 chars (Middle 16)".
- Switch letter case between lowercase and uppercase.
Tip:MD5 is a hash function, not reversible encryption. It should not be used for password storage.
When is this useful?
- Verifying that a downloaded file matches the official version
- Comparing whether two text strings are identical
- Generating fixed-length identifiers for data indexing
What is the difference between MD5 and SHA-256?
MD5 produces a 128-bit hash and is fast, but has known collision vulnerabilities. SHA-256 produces a 256-bit hash and is more suitable for security-critical applications.
Can MD5 be reversed to recover the original text?
No, MD5 is a one-way function. The original input cannot be recovered from the hash, though common strings can often be found via rainbow tables.
Does the same text always produce the same MD5?
Yes, MD5 is deterministic — the same input always produces the same output. This makes it useful for verifying file and data integrity.
Why should MD5 not be used to store passwords?
MD5 computes too quickly, making it vulnerable to brute-force and rainbow table attacks. Use bcrypt or Argon2 instead for password hashing.
