public static class CryptoFunctions.SHA1Function
extends Object
implements DrillSimpleFunc

sha() / sha1(): 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. > select sha1( 'testing' ) from (VALUES(1));
