It is a value that is known to the sender.

It is also called as private key cryptography.

It is a science that applies complex

mathematics and logic to design strong encryption

methods.

It is pair of algorithms that take a key and convert plaintext to ciphertext and

back.

The original message in its original legible form.

One key is used for data encryption and another for data decryption.

In hardware-based cryptography, it is dependent on the operating system.

In software-based cryptography, it uses shared hardware, thus slower to execute.

In software-based cryptography, software implementations can be easily reverse engineered.

It is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes or dits and dahs.
