<h2>Encryption and Decryption APIs</h2>
|
||
|
|
|
||
|
|
<p>The Encryption and Decryption APIs allow you to store information or to communicate
|
||
|
|
with other parties while preventing uninvolved parties from understanding the
|
||
|
|
stored information or understanding the communication. Encryption transforms
|
||
|
|
understandable text (cleartext) into an unintelligible piece of data (ciphertext).
|
||
|
|
Decrypting restores the cleartext from the ciphertext. Both processes involve a
|
||
|
|
mathematical formula (algorithm) and secret data (key).
|
||
|
|
