PHP speed test and comparison code for various encryption algorithms and Hash Algorithms

This article mainly introduces the speed test and comparison code for various encryption algorithms and Hash algorithms in PHP. If you want to select an encryption algorithm, you can consider it as a performance factor. For more information, see

The Hash algorithm of PHP is quite common. The current MD5 algorithm is sometimes not safe, so we need to use other algorithms in Hash_algos (). The following is a performance comparison.

Php code:

Define ('testtime', 50000); $ algos = hash_algos (); foreach ($ algos as $ algo) {$ st = microtime (); for ($ I = 0; $ I <testtime; $ I ++) {hash ($ algo, microtime (). $ I) ;}$ et = microtime (); list ($ ss, $ si) = explode ('', $ st); list ($ es, $ ei) = explode ('', $ et); $ time [$ algo] = $ ei + $ es-$ si-$ ss;} asort ($ time, SORT_NUMERIC ); echo ""; print_r ($ time ); array ([crc32b] => 0.14577506593323 [crc32] => 0.14600901216125 [adler32] => 0.14769597711182 [md4] => 0.1584680151825 [md5] => 0.15956400747681 [salsa20] => 0.16176804933166 [salsa10 => 0.16325911569214 [tiger128, 3] => 0.16543607070923 [sha1] => 0.16547892630005 [tiger160, 3] => 0.16672711079407 [tiger192, 3] => 0.16793211837769 [tiger128, 4] => 0.16802901655579 [shares'] => 0.16959108877563 [tiger160, 4] => 0.1713979150238 [tiger192, 4] => 0.1717759589386 [sha256] => 0.17396298696899 [ripemd256] => 0.17431005943298 [ripemd128] => 0.17437094918823 [ripemd320] => 0.17870710316467 [haval160, 3] => 0.18147005220032 [haval256, 3] => 0.18150104528809 [haval224, 3] => 0.18176211320496 [sha512] => 0.18234492471313 [haval192, 3] => 0.18296506645203 [ripemd160] => 0.18318411643982 [haval128, 3] => 0.18408892243958 [sha384] => 0.18502903718567 [haval128, 4] => 0.18848111178589 [haval256, 4] => 0.18875202952576 [haval160, 4] => 0.1895639828186 [haval.pdf, 4] => 0.19041207319641 [haval192, 4] => 0.19101205462646 [whirlpool] => 0.19728892146301 [haval256, 5] => 0.19996902294922 [haval160, 5] => 0.20026498704529 [haval192, 5] => 0.20072503967285 [haval128, 5] => 0.20132308227539 [haval128, 5] => 0.2025869493103 [gost] => 0.24892493852234 [snefru256] => 0.28652299385071 [snefru] => 0.29043891609192 [md2] => 0.6300178873291)
