Easycluster recently requires users to be created and a user account can be created on Linux. It is natural that the background program calls the useradd command line, passwords are troublesome. Check the useradd manual. You can specify a password

The irreversible cryptographic functions are: MD5 (), Crypt () MD5 () is used to calculate MD5. The syntax is: string MD5 (string str); Crypt () encrypts the string with the UNIX standard cryptographic DES module. This is a one-way cryptographic

The irreversible cryptographic functions are: MD5 (), Crypt () MD5 () is used to calculate MD5. The syntax is: string MD5 (string str); Crypt () encrypts the string with the UNIX standard cryptographic DES module. This is a one-way cryptographic

The crypt function is used for encryption. Currently, the encryption methods on Linux are MD5, Des, and 3 DES. MD5 and des are used more frequently on the RedHat platform. The original form of the crypt function is: Char * crypt (const char *
