OBSOLETE
SYNOPSIS
string sha1(string arg [, int iterations ])
string sha1(bytes arg [, int iterations ])
string sha1(int * arg [, int iterations ])
DESCRIPTION
Create and return a SHA1 message digest from <arg>.
<arg> may be a string, a byte sequence, or an array of numbers
(each considered to be a byte, ignoring all but the lowest 8 bits).
A string is converted to a UTF-8 byte sequence of which then the
digest will be created.
If <iterations> is given as a number greater than 0, it is
the number of iterations used in the digest calculation. If omitted,
the driver executes just one iteration.
The efun costs 5 ticks per iteration.
EXAMPLES
string s;
s = sha1("Hello");
s = sha1( ({ 'H', 'e', 'l', 'l', 'o' })
HISTORY
Introduced in LDMud 3.3.523.
LDMud 3.3.712 added number arrays as argument, and the number
of iterations.
LDMud 3.3.717 added the iteration-based evaluation cost.
Since LDMud 3.3.719 obsoleted by hash().
