openssl_random_pseudo_bytes — Generate a pseudo-random string of bytes 描述 代码语言:javascript 复制 stringopenssl_random_pseudo_bytes(int $length[,bool&$crypto_strong]) 生成一串伪随机字节,其中由length参数确定的字节数。 它还指示是否使用密码强的算法来生成伪随机字节,并通过可选crypto_strong参数执行...

Generate the random password file Use the following command to generate the random key: openssl rand -base64 128 -out key.bin 1. Do this every time you encrypt a file. Use a new keyevery time! Encrypt the file with the random key ...
can be used to generate pseudo-random bytes. The-base64flag will base64 encode the output, providing you with a random string that can be used as a password or for other applications that require a random string. Just make sure that the number of bytes isdivisible by threeto avoid ...
Generate random bytes with length of length. If private is set to true, a private PRNG instance is used so that a compromise of the "public" PRNG instance will not affect the secrecy of these private values.The bytes generated will have a security strength of at least strength bits....
