Now if MD5 is a one way function, how do we decrypt it ? We actually don't "decrypt" MD5, we use this word because it's easy to understand, but hashingįunction cannot be decrypted. The hash of password you enter, if they match the passwords were the same. When you enter a password on a website it is (most of the time) stored as hash, then when you come back this hash is compared to Thanks to this, webmasters are not in capacity to know your plain passwordįrom their database. This is also why it is used to sign files and also to store passwords. Meaning that you cannot calculate the plaintext that was hashed only looking at the hash. Since MD5 in a hashing function, it is not reversible. While the same word without the Capital "P" gives this hash : If you type the word "Password" with a capital, it will produce this hash :
The hash produced by MD5 is supposed to be unique (it cannot be since 128-bits even if very large is finite), so for instance You can find out more about collisions here.ĭespite being insecure, MD5 is still widely used as a file fingerprint (such as SHA-1) and password storageīy webmasters that are not well informed about security. In 1996 actual collisions were also found on MD5 which is considered as insecure since Suffered from security breaches (collisions were found very early). MD5 was created in 1991 as a replacement of MD4 algorithm, that, however being a 128-bits algorithm too, This produces a digital fingerprint of the file or text and thus allows to sign it
HASHLIB MD5 PASSWORD GENERATOR ONLINE CODE
MD5 (or Message Digest 5), is a cryptographic function that allows you to create a 128-bits (32 characters in hexadecimal since you only needĤ bits to code hexadecimal) "hash" from any input up to 2^64 bits.
