=head1 NAME
|
||
|
||
ZUC_set_key, ZUC_generate_keystream, ZUC_generate_keyword - ZUC Stream Cipher
|
||
|
||
=head1 SYNOPSIS
|
||
|
||
#include <openssl/zuc.h>
|
||
|
||
void ZUC_set_key(ZUC_KEY *key, const unsigned char *user_key, const unsigned char *iv);
|
||
void ZUC_generate_keystream(ZUC_KEY *key, size_t nwords, uint32_t *words);
|
||
uint32_t ZUC_generate_keyword(ZUC_KEY *key);
|
||
|
||
=head1 DESCRIPTION
|
||
|
||
ZUC_set_key() sets up the B<ZUC_KEY> key using the B<user_key> and initial vector B<iv>.
|
||
|
||
ZUC_set_key()通过用户的密钥B<user_key>以及初始向量B<iv>来设置密钥结构B<ZUC_KEY>。
|
||
|
||
ZUC_generate_keystream() computes 32-bit keywords for B<nwords> times by a B<ZUC_KEY> structure, and stores them in the given B<words> array(pointer).
|
||
|
||
ZUC_generate_keystream()通过函数参数中的B<ZUC_KEY>结构计算B<nwords>个32-bit的密钥字，并装入给定的B<words>数组中。
|
||
|
||
ZUC_generate_keyword() is simliar to ZUC_generate_keystream(), but computes keyword only once and return this value.
|
||
|
||
ZUC_generate_keyword()与ZUC_generate_keystream()相似，但只计算一次并直接返回该密钥字的值。
|
||
|
||
=head1 RETURN VALUES
|
||
|
||
ZUC_set_key() and ZUC_generate_keystream() have no return value.
|
||
|
||
ZUC_set_key()和ZUC_generate_keystream()无返回值。
|
||
|
||
ZUC_generate_keyword() returns a 32-bit unsigned integer.
|
||
|
||
ZUC_generate_keyword()返回一个32位无符号整数。
