像openssl这样的成熟解决方案都会自动识别这一类随机性不足的情况，并阻塞读取操作以确保安全。
就需要注意多线程安全问题。 一是OpenSSL需要编译成多线程安全版本，二是需要为OpenSSL注册两个回调...

Supposedly there was a bug pre 5.3.4 causing openssl_random_pseudo_bytes() to run painfully slow, occassionally causing timeout errors. I'm not sure if I should try to use openssl_random_pseudo_bytes() with Crypt() or something like the above method using mt_rand() and...
$token = base64_encode( openssl_random_pseudo_bytes(32)); The only reason for the base64_encode() call is to make sure that the value provided will not break your HTML layout. Looks like we need to updateAura.Sessionto use openssl when available and fall back to mt_rand() when it'...
