Applying MD5 Algorithm In Android

Hello developers, have you ever given a thought about securing your content when it is being used in communication? If yes then this blog might help you in achieving so.

MD5 stands for Message Digest(5 denotes the series), which is a hashing algorithm used for generating the fingerprint of the content. It was designed in 1991 by Ronald Rivest at MIT.

MD5 algorithm is a one way hashing process which means you cannot generate original text from the hash code.It always produces the same output for the similar input, and this property is used for checking the data integrity. You can compare the two hash codes at destination(one which is received from server and one which is already present at destination) and check whether the files contains the same content or not.

Upload Failed : You uploaded a debuggable APK

It was quite late in the evening and I was about to wrap up my work. Suddenly I got a call form my client in Skype and he shared his concerns of uploading the build to production.
