to 4096 bits. The RSA private key may be retained and used within the secure boundary of the cryptographic coprocessor. This capability is a requirement to be a SET Certificate Authority. The public key and the key name for the private key are stored in the ICSF public key data set (PK...
可以试一下,我们用key.pem(之前的私钥)是没法加密的,所以我们公布出去私钥其他人是根本用不了的 $ openssl rsautl -encrypt -pubin -inkey key.pem -in hello.txt -out cipher.txt unable to load Public Key 为什么私钥和公钥文件格式不一样?实际的私钥文件里除了包含密钥值以外,还记录了用于产生私钥的原始...
