后端

public function encrypt2($input = ''){

$pk = "123454536f667445454d537973576562"

$iv = substr("1234577290ABCDEF1264147890ACAE45", 0, 16)

// $t = 'T10515'

$encrypted = ( mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $pk, $input, MCRYPT_MODE_CBC,$iv) )

return base64_encode($encrypted)

}

public function decrypt2($encrypted){

$pk = "123454536f667445454d537973576562"

$iv = substr("1234577290ABCDEF1264147890ACAE45", 0, 16)

// $t = 'T10515'

// $encrypted = "b7y/JPJFNTfxNVR8H4NNtw=="

return mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $pk, base64_decode($encrypted), MCRYPT_MODE_CBC, $iv)

}

可以推断， js 部分实际只使用了 iv 的 16 位长度

ps：

js加密后默认会base64_encode

使用php解密需要base64_decode后才一致

所以使用js加密和php解密时候需要注意，php端要先base64_decode再解密，例：

js加密的串是$t=b7y/JPJFNTfxNVR8H4NNtw==

php需要

$password= trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $pk,base64_decode( $t), MCRYPT_MODE_CBC, $iv))

则$password才能正确解析出来

需要引入的两个js文件
