openssl ecc certificate

ECC process is very different from RSA, ECC involves a lot of additional concepts, such as group and so on, in addition ECC contains two different sets of mechanisms, this is ECDSA and ECDH, these two sets of mechanisms unified in ECC, in non-ECC

The process of ECC is quite different from that of RSA. ECC involves many additional concepts, such as group. In addition, ECC includes two completely different mechanisms, namely, ECDSA and ecdh, these two sets of mechanisms are unified in ECC. In

After learning about the ECC concept, we know the meaning of group. In fact, group defines a curve, A, B, and order, in the implementation of OpenSSL, the Group also has an ec_method struct, which contains a series of functions. As the name suggests,

1 HTTPS Protocol OverviewHTTPS can be thought of as HTTP + TLS. The HTTP protocol is familiar, and most Web applications and websites are now transmitted using the HTTP protocol. TLS is the Transport Layer encryption protocol, its predecessor is the

HTTPS attackFull-site HTTPS is planning the trend of the draftsuch as: Baidu, AliThe role of HTTPSCIAThe solution is the data in the transmission process of tampering, stealing "from the injection of malicious code, many for link

First, data encryption methodEncryption is divided into: one-way encryption, symmetric encryption and public key cryptography.1. Symmetric encryptionSymmetric encryption: Using the encryption method of single-key cryptosystem, the same key can be

Functional Applications: Message digest, which generates a message digest for the file or data, and the message digest can only verify the integrity of the data, such as Sha, MD5 Data encryption and decryption: Encrypt and decrypt

Symmetric encryption: Des,3des AESFunction: Confidentiality is guaranteed onlyAsymmetric encryption: (Public key cryptography): It is calculated by mathematical functions. Common RSA,DSS (only encrypted, not signed), ECC (elliptic curve algorithm,
