SYNOPSIS string sha1 (string arg [ , int iterations ] ) string sha1 (int * arg [ , int iterations ] ) DESCRIPTION Create and return a SHA1 message digest from . may be a string, or an array of numbers (each considered to be a character, ignoring all but the lowest byte). If 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. SEE ALSO crypt(E), md5(E), md5_crypt(E), hash(E), hmac(E)
