[PHP]PHP 使用 SHA256、SHA512 等 演演算法的寫法


[PHP]PHP 使用 SHA256、SHA512 等 演演算法的寫法 簡版






[PHP]PHP 使用 SHA256、SHA512 等 演演算法的寫法

類型:
PHP

PHP 有 md5()sha1() ... 等等 function,不過現在建議使用 SHA224 以上(註),在 PHP 要怎麼寫呢?

註:下述摘錄自此篇:Mobilefish.com - MD5, SHA1, SHA224, SHA256, SHA384, SHA512 and RIPEMD160 hash generator



MD5 is considered cryptographically broken and is unsuitable for further use.

The SHA1 algorithm might not be secure enough for ongoing use. It is recommended not to use SHA1.

SHA224: SHA224 produces a 224-bit (28-byte) hash value, typically rendered as a hexadecimal number, 56 digits long.

SHA256: SHA256 produces a 256-bit (32-byte) hash value, typically rendered as a hexadecimal number, 64 digits long.

SHA384: SHA384 produces a 384-bit (48-byte) hash value, typically rendered as a hexadecimal number, 96 digits long.

SHA512: SHA512 produces a 512-bit (64-byte) hash value, typically rendered as a hexadecimal number, 128 digits long.

RIPEMD160: RIPEMD160 produces a 160-bit (20-byte) hash value, typically rendered as a hexadecimal number, 40 digits long.

PHP 使用 SHA256、SHA512 等 雜湊演演算法的寫法

雜湊(Hash)演演算法越來越多,PHP 直接做了 hash() 來用,直接指定要用哪個雜湊演演算法即可。

PHP hash() 使用範例

PHP hash() 有支援哪些雜湊演演算法呢?

可以使用 hash_algos() 來查詢,範例如下:

md2

[1] => md4

[2] => md5

[3] => sha1

[4] => sha224

[5] => sha256

[6] => sha384

[7] => sha512

[8] => ripemd128

[9] => ripemd160

[10] => ripemd256

[11] => ripemd320

[12] => whirlpool

[13] => tiger128,3

[14] => tiger160,3

[15] => tiger192,3

[16] => tiger128,4

[17] => tiger160,4

[18] => tiger192,4

[19] => snefru

[20] => snefru256

[21] => gost

[22] => gost-crypto

[23] => adler32

[24] => crc32

[25] => crc32b

[26] => fnv132

[27] => fnv1a32

[28] => fnv164

[29] => fnv1a64

[30] => joaat

[31] => haval128,3

[32] => haval160,3

[33] => haval192,3

[34] => haval224,3

[35] => haval256,3

[36] => haval128,4

[37] => haval160,4

[38] => haval192,4

[39] => haval224,4

[40] => haval256,4

[41] => haval128,5

[42] => haval160,5

[43] => haval192,5

[44] => haval224,5

[45] => haval256,5
