Description

From the listing uploaded by “apps”.

Decrypto is an application that provides a range of encryption and decryption tools. Over 25 traditional ciphers are implemented such as the Caesar code, ASCII code or the code of Vigenère. An explanation and a short history are provided with each type of encryption to better understand them. If you have an encrypted message, but you do not know the type of cipher used, the application can try to decrypt the message for you! Indeed, a tool allows to test all the different types of ciphers and display the possible results based on a dictionary. A frequency analysis tool for an encrypted text is also available. You can know exactly the number of occurrences of each letter in the encrypted text in a few clicks. Even better, the application can perform a frequency analysis and replace each letter of the encrypted message by the most likely letter! You can also save your encrypted messages to view them later or share them with your friends! Tags: encryption, cryptography, encrypt, decrypt, cipher, geocaching.

Decrypto APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the Decrypto APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Unknown. After downloading, check that the file's MD5 is 4279b20ffac277cffdc09d7185025e89.
