Secure programming with the OpenSSL API First, Concept: 1. What is SSL.   SSL is an abbreviation, the full name is Secure Sockets Layer.   It is the standard that supports secure communication over the Internet and integrates data cryptography into

Preface openSSL is a powerful encryption tool. many of us are already using openSSL to create RSA private key or certificate signature requests. However, you can use openSSL to test the computer. speed? You can also use it to encrypt files or

Encryption Algorithm: Symmetric encryption algorithm: Des, idea, RC2, RC4, AES, Skipjack ...... Asymmetric encryption algorithm: RSA, DSA, diffiehellman, PKCS, PGP ...... The one-way hash algorithm is a packet Digest algorithm, although some are

Using OpenSSL utilities An OpenSSL command line takes the following form: openssl utility arguments For example: openssl x509 -in OrbixCA -text Each Command is individually described in this Appendix. To get a list of the arguments

OpenSSL encoding rules1. data encoding format Openssl data encoding rules are based on ans.1. What is ans.1? An Explanation on top of the project ASN.1 (Abstract Syntax Notation One) is a structured Description Language, which consists of two parts:

Symmetric encryption tool, understanding the principle of symmetric encryption is very simple, the principle section is shown below. OpenSSL enc-ciphername [-in filename] [-out filename] [-pass arg] [-e] [-d] [-a/-base64] [-k password] [-S SALT]
