Added small changes that missed PR #17209 (#17552)
Browse files Browse the repository at this point in the history 
* Added support for encryption AES encryption algorithms.

* Added CryptographyOptions and ensured the initialization vector is populated before attempting to perform any local cryptography operations on symmetric keys.

* Added APIs that accept CryptographyOptions to CryptographyClient.

* Fixed Javadoc issues.

* Fixed checkstyle issues. Added samples.

* Added checkstyle exceptions.

* Fixed test and spotbugs issues.

* Applied PR feedback and added local tests.

* Made the EncryptOptions and DecryptOptions constructor package-private, as well as their children's, and made them have factory methods for creating the former to help with discoverability.

* Fixed build issues.

* Changed EncryptOptions and DecryptOptions to use a factory model.

* Added iv, additionalAuthenticatedDate and authenticationTag to EncryptResult.

* Made `plainText` and `cipherText` all lowercase.

* Reverted capitalization change.

* Added null check for `iv` in local decryption.
