Simple encryption and decryption java

Key size assigned here is 64 bits. It works only for the key size of 64 bits. Encryption and decryption method is written based on DES algorithm.

Try using the -base64 option. Seems like duplicate of stackoverflow. Side comment: if you want ECB mode, then specify it. Relying on defaults is an unwise thing to do. Add a comment. A one-time-pad is very easy to create; all you need is a random sequence of bytes the same length as the data you are encrypting. BASE64Encoder is used to represent the ciphered array of bytes, not the actual input. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Probably we will go in detail another time. However there is always a need for simple encryption and decryption process which we can easily incorporate in our code with out many dependency. While looking for such solution I came across this simple Blowfish implementation, which is very easy to understand and implement. Here is the most simple solution on how to easily encrypt and decrypt text in Java. Here is the decrypt method.
