> I would like to propose hash functions (implemented as UDFs): 
> Optionally we can also add for below functions variants which return hex string instead of bytes. 
> # MD5
> Calculates an MD5 128-bit checksum of string or bytes and returns it as a bytes
> {code:java}
> SELECT MD5("Some String") as md5;
> {code}
> # SHA1
> Calculates a SHA-1 hash value of string or bytes and returns it as a bytes.
> {code:java}
> SELECT SHA1("Some String") as sha1;
> {code}
> # SHA256
> Calculates a SHA-256 hash value of string or bytes and returns it as a bytes
> {code:java}
> SELECT SHA256("Some String") as sha256;
> {code}
> # SHA512
> Calculates a SHA-512 hash value of string or bytes and returns it as a bytes.
> {code:java}
> SELECT SHA512("Some String") as sha512;
> {code}
