don't be so crazy! The more complex the branching, the harder it is for us to determine what we are doing.10. AliasesGit allows us to create shortcuts (aliases) for commonly used commands. For example, if we don't want to enter Git commit-m "some comment" every time, but instead enter git C "some comment", we can add an alias to the GIT global configuration, like this:git config--global alias.c ' commit-m 'Here is the list of aliases I used:git config--global alias.c ' commit-m 'git config--glo
Asymmetric encryption algorithm is also called
This algorithm can only be decrypted with the corresponding private key if the public key is used for encryption, or it can only be decrypted with the corresponding public key if encrypted with the private key. It is almost impossible to derive the private key from the public key (such an algorithm can be implemented using some irreversible functions)!
OpenSSL supports RSA, DSA, DH three different asymmetric encryption algorithms. Here we'll expl
