Read more about C Programming Language . Encrypted or encoded strings are most of the time used during transmission over the internet. the key and the string that needs to be encrypted. For example, if we use an offset of 4, every occurrence of 'A' will be replaced by 'E', every occurrence of 'B' will be replaced by 'F', and so forth. Encrypt and Decrypt are very important data when code with C#. Learn about RSA algorithm in Java with program example. What is Encrypt and Decrypt? What you really want is a pair of maps, but not lowercase and uppercase - instead you want forward and reverse (with both upper and lower in the same map). If a password was used to create the encryption session key, that same password must be entered to create the decryption session key. Modern Examples of Symmetric Authenticated Encryption of a string. I would like to encrypt and decrypt a string in C# and C++ Qt.
