| 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(). |
