Data encryption is the process of converting readable information (plaintext) into an unreadable format (ciphertext) to protect it from unauthorized access.
It is a method of preserving data confidentiality by transforming it into ciphertext, which can only be decoded using a unique decryption key produced at the time of the encryption or before it. The conversion of plaintext into ciphertext is known as encryption.
By using encryption keys and mathematical algorithms, the data is scrambled so that anyone intercepting it without the proper key cannot understand the contents.
PROCESS
The readable message called plain text before sending it over a network, the sender uses an encryption key and the encryption process of converting readable text to unreadable ciphertext takes place. This cipher text travel over the internet, if someone intercepts it, they cannot understand without the right key. When the ciphertext reaches the intended recipient, they use the matching decryption key and a decryption process to turn the unreadable ciphertext back into the original.
