What is MD5?

MD5 (Message Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value. Typically expressed as a 32-digit hexadecimal number, MD5 has been utilized in a wide variety of security applications and is also commonly used to check the integrity of files.

Common Use Cases for MD5

Data Integrity

Verifying that a file has not been altered during transfer. If the hash matches the source, the file is intact.

Checksums

Software developers often provide MD5 checksums for users to validate their downloads.

Database Indexing

Creating unique keys for database entries where the original content length varies.

Fingerprinting

Identifying specific data sets or files without storing the actual content.

Is MD5 Secure for Passwords?

No. While MD5 was once used for password hashing, it is now considered cryptographically broken and unsafe for security purposes. It is vulnerable to collision attacks (where two different inputs produce the same hash) and is too fast, making it susceptible to brute-force attacks. For password storage, modern algorithms like bcrypt, Argon2, or PBKDF2 are recommended. However, MD5 remains excellent for non-cryptographic purposes like checksums and data integrity verification.

Frequently Asked Questions

Can I decrypt an MD5 hash?
No, MD5 is a one-way hash function. It cannot be reversed to reveal the original input. However, because it is fast, attackers can use "rainbow tables" to look up the input for common hashes.
What is the length of an MD5 hash?
An MD5 hash is always 128 bits long. When represented in hexadecimal (base 16), it is a string of 32 characters (0-9 and a-f).
