> Add Crypto and Hash Functions
> -----------------------------
>
> Key: DRILL-5634
> URL: https://issues.apache.org/jira/browse/DRILL-5634
> Project: Apache Drill
> Issue Type: New Feature
> Components: Functions - Drill
> Affects Versions: 1.10.0
> Reporter: Charles Givre
> Labels: doc-impacting
> Fix For: 1.11.0
>
>
> This library contains a collection of cryptography-related functions for
> Apache Drill. It generally mirrors the crypto functions in MySQL. The
> package includes:
> * **`aes_encrypt()`/ `aes_decrypt()`**: implement encryption and decryption
> of data using the official AES (Advanced Encryption Standard) algorithm,
> previously known as “Rijndael.”
> `AES_ENCRYPT()` encrypts the string `str` using the key string `key_str` and
> returns a binary string containing the encrypted output. `AES_DECRYPT()`
> decrypts the encrypted string `crypt_str` using the key string `key_str` and
> returns the original cleartext string. If either function argument is NULL,
> the function returns NULL.
> ```sql
> > SELECT aes_encrypt( 'encrypted_text', 'my_secret_key' ) AS aes FROM
> > (VALUES(1));
> +---------------------------+
> | aes |
> +---------------------------+
> | JkcBUNAn8ByKWCcVmNrKMA== |
> +---------------------------+
> > SELECT aes_encrypt( 'encrypted_text', 'my_secret_key' ) AS encrypted,
> aes_decrypt(aes_encrypt( 'encrypted_text', 'my_secret_key'
> ),'my_secret_key') AS decrypted
> FROM (VALUES(1));
> +---------------------------+-----------------+
> | encrypted | decrypted |
> +---------------------------+-----------------+
> | JkcBUNAn8ByKWCcVmNrKMA== | encrypted_text |
> +---------------------------+-----------------+
> ```
> * **`md5(<text>)`**: Returns the md5 hash of the text.
> (https://en.wikipedia.org/wiki/MD5)
> Usage:
> ```sql
> > select md5( 'testing' ) from (VALUES(1));
> +-----------------------------------+
> | EXPR$0 |
> +-----------------------------------+
> | ae2b1fca515949e5d54fb22b8ed95575 |
> +-----------------------------------+
> ```
> * **`sha(<text>`) / `sha1(<text>)`**: Calculates an SHA-1 160-bit checksum
> for the string, as described in RFC 3174 (Secure Hash Algorithm).
> (https://en.wikipedia.org/wiki/SHA-1) The value is returned as a string of
> 40 hexadecimal digits, or NULL if the argument was NULL. Note that `sha()`
> and `sha1()` are aliases for the same function.
> ```sql
> > select sha1( 'testing' ) from (VALUES(1));
> +-------------------------------------------+
> | EXPR$0 |
> +-------------------------------------------+
> | dc724af18fbdd4e59189f5fe768a5f8311527050 |
> +-------------------------------------------+
> ```
> * **`sha2(<text>`) / `sha256(<text>)`**: Calculates an SHA-2 256-bit checksum
> for the string. (https://en.wikipedia.org/wiki/SHA-2) The value is returned
> as a string of hexadecimal digits, or NULL if the argument was NULL. Note
> that `sha2()` and `sha256()` are aliases for the same function.
> ```sql
> > select sha2( 'testing' ) from (VALUES(1));
> +-------------------------------------------------------------------+
> | EXPR$0 |
> +-------------------------------------------------------------------+
> | cf80cd8aed482d5d1527d7dc72fceff84e6326592848447d2dc0b0e87dfc9a90 |
> +-------------------------------------------------------------------+
> ```
> Additionally, there are also `sha384(<text>)` and `sha512(<text>)` functions
> which return SHA-2 hashes with 384 and 512 bit checksums.
