使用openssl的工具,针对rsa非对称加密,private key和public key是成对出现的,从数学上来说是一对一的关系。 也就是一个private key只能产生一个public key。 而且,如果在命令行中(Ubuntu操作系统,非windows)使用openssl的工具使用 -text选项会出现可读的以类似于十六进制显示的 private key,会出现modulus和exponent等...
Decrypt the random key with our private key file If you want to decrypt a file encrypted with this setup, use the following command with your privte key (beloning to the pubkey the random key was crypted to) to decrypt the random key: openssl rsautl -decrypt -inkey privatekey.pem -in ...

从一个JKS的keystore中导出public key (certificate)keytool -export -alias mykey -keystore keystore -file exported.crt 转换成PEM格式，这个格式使用更广 openssl x509 -out exported-pem.crt -outform pem -text -in exported.crt -inform der 导出private key（请参考）: 下载文件ExportPriv....
上述得到的private key是PKCS#8 PEM格式,使用如下命令才能转换成apache可以使用的RSA格式 openssl pkcs8 -inform PEM -nocrypt -in exported-pkcs8.key -out exported.key 现在可以把得到的public key(certificate) 和private key打包在一起,转换成windows平台常用的PKCS12格式 ...
公钥(Public Key): 用于加密数据,可以公开。 私钥(Private Key): 用于解密数据,必须保密。 2.3.3. 证书 (Certificates) 数字证书 (Digital Certificate): 用于验证实体身份的电子文件。 在这个章节中,我们只是触及了OpenSSL的表面。但正如《道德经》所说:“千里之行,始于足下。”(“A journey of a thousand mil...
The main OpenSSL Git repository is private. There is a public GitHub mirror of it atgithub.com/openssl/openssl, which is updated automatically from the former on every commit. A local copy of the Git repository can be obtained by cloning it from the GitHub mirror using ...
"OpenSSL::PKey::RSAError: padding check failed" error received if the private key used to try and decrypt the value is not the pair of the public key used to encrypt the value. This can be received if the client/admin pem is regenerated after doing the encryption with chef-vault and th...
