Welcome on MD5Online
MD5Online offers several tools related to the MD5 cryptographic algorithm.
MD5 is not a reversible function. Since 2012 we have built the largest database of hashes (1,154,870,420,517 to be precise)
that you can use with these tools to decrypt hashes.
Test our tools!
Secure your password by encrypting it into an MD5 hash.
Use our database and other sources to try decrypting a MD5 hash and find the corresponding word.
Many hashes to decrypt? No problem, use our list tool where you can copy and paste all your hashes.
Decryption modes
MD5Online offers two decryption modes for the decryption tools:
| Quick search | In-depth search | |
|---|---|---|
| Success rate | Lower |  High |
| Methods | Dictionaries | Dictionaries Databases External sources Bruteforce |
| Daily limits | 100 hashes per 24h | Unlimited |
| Constant search | One-time try | One try on first submit Automatic regular attempts |
| API access | No | Yes |
Quick search
The quick search is free of charge until 100 hashes per day.
The search will only be done in our dictionaries, so the success rate is not as high as the in-depth search.
Common words and most-used passwords will be found with this search mode.
There is a lower probability to decrypt hashes with random or special characters.
You can expect much more sucess with the in-depth search.
In-depth search
For more hashes or a better chance to decrypt them, we recommend the in-depth search.
With this method, you unlock access to all the premium ressources of MD5Online.
In addition to the dictionaries from the free method, we'll use other tools to help you to decrypt your hashes.
We can't reveal exactly how it works, but you have access to more dictionaries, a giant database, external sources and a brute-force architecture.
The success rate with this option is over 86%.
Moreover, we will constantly try to decrypt the hashes we didn't find on the first try (including bruteforce on a dedicated computer).
You'll receive an email each time we decrypt a new one.
Our goal is really to help you the most we can to decrypt your hashes.
Last but not least, this method can be use with your API, so you can automate the process on your side to save time with this.
