zmq_z85_encode(3) ØMQ Manual - ØMQ/4.1.0
Name
zmq_z85_encode – 使用Z85算法对一个二进制秘钥进行加密，输出可打印的文本
Synopsis
char *zmq_z85_encode (char *dest, uint8_t *data, size_t size);
Description
zmq_z85_encode()函数会对data参数和size参数指定的二进制数据块进行加密，并以字符串形式存储在dest参数指定的空间内。这个二进制数据块的大小必须是可以被4整除的。dest参数指定的空间大小至少满足size * 1.25 + 1，最后1个字节用来存储字符串结束符。一个32B长的密码会被加密后会变成40B长再加1B的空字符。
加密方式遵循ZMQ RFC 32 规格。
Return value
如果zmq_z85_encode()函数执行成功，则会返回dest的指针，否则返回NULL。
Example
加密一个curve密码
1 #include <sodium.h>
2 uint8_t public_key [32];
3 uint8_t secret_key [32];
4 int rc = crypto_box_keypair (public_key, secret_key);
5 assert (rc == 0);
6 char encoded [41];
7 zmq_z85_encode (encoded, public_key, 32); puts (encoded);
