MD5 is a one-way, non-secure digest for checksums and lookups. It is not encryption and cannot be decrypted. Use SHA-256 or a password-specific KDF such as Argon2id for security-sensitive work.
사용 방법
사용 방법
- Enter or paste text into the input field.
- Generate the MD5 digest locally.
- Copy the hexadecimal result when ready.
Local MD5 digest
The page computes the MD5 digest in your browser and displays lowercase hexadecimal output. Your text is not uploaded.
Checksums and lookups only
MD5 is cryptographically broken and should not protect passwords, signatures, or other security-sensitive data.
One-way operation
MD5 is a hash, not encryption. There is no decrypt operation that reliably recovers the original text. Use SHA-256 for general integrity and Argon2id, scrypt, or PBKDF2 with a salt for passwords.
자주 묻는 질문
더 알아보기
Can MD5 be decrypted?
No. MD5 is a one-way digest, not encryption. Guessing or lookup attacks may recover common inputs, but the digest itself cannot be reversed reliably.
What is MD5 useful for?
It remains useful for legacy compatibility, non-adversarial checksums, and identifying known content when collision resistance is not required.
Is my text uploaded?
No. The digest is calculated locally in your browser.
Should I use MD5 for passwords?
No. Use a password-specific KDF such as Argon2id, scrypt, or PBKDF2 with a unique salt.
