1)电子密码本模式 Electronic Code Book(ECB):最基本的加密模式,也就是通常理解的加密,相同的明文将永远加密成相同的密文,无初始向量,容易受到密码本重放攻击,一般情况下很少用。 2)密码分组链接模式 Cipher Block Chaining(CBC):明文被加密前要与前面的密文进行异或运算后再加密,因此只要选择不同的初始向量,相同的...

In order to reduce the size of the oqsprovider, it is possible to limit the number of algorithms supported, e.g., to the set of NIST standardized algorithms. This is facilitated by setting theliboqsbuild option-DOQS_ALGS_ENABLED=STD. ...
>是个unix系统下常见的接口,但windows平台的MSVC编译器并没有提供这个接口( Cygwin5 and MingW现在已经提供了dirent接口),对于跨平台的项目开发就会带来一些麻烦,如果在...MSVC下编译时可能因为windows平台缺少这个接口就要为windows平台另外写一些代码。...在网上一搜索,已经有人在windows下为MSVC实现了dirent.h接口(...

3) have configured SSLv2 ciphersuites (these are not in the default ciphersuite list) OpenSSL 1.1.1 does not have SSLv2 support and therefore is not vulnerable to this issue. The underlying error is in the implementation of the RSA_padding_check_SSLv23() function. This also affects the ...
方法/步骤 1 首先，OpenSSL建立自己的CA， 环境准备，需要准备一个目录放置CA文件，包括颁发的证书和CRL(Certificate Revoke List)，选择目录/var/MyCA。我们在/var/MyCA下建立两个目录，certs用来保存我们的CA颁发的所有的证书的副本；private用来保存CA证书的私钥匙。2 然后，除了生成钥匙，在我们的CA体系中还需要...
