GoRandomLib

A collection of useful yet random go funtions in one libary

Functions

1. extractValue(content, key string) string: Extracts a value from a string content based on a given key. It splits the content string using the key, then returns the first word after the key.

2. dirExists(path string) bool: Checks if a directory exists at the specified path.

3. readFile(filename string) (string, error): Reads the content of a file specified by filename and returns it as a string. It also returns an error if any.

4. getChars(s string, num int) string: Returns the first num characters from the string s.

5. CreateSHA256String(input string) string: Calculates the SHA-256 hash of the input string and returns it as a hexadecimal string.

6. RandomStringWithCharset(length int, charset string) string: Generates a random string of the specified length using the provided charset.

7. RandomString(length int) string: Generates a random string of the specified length using the default charset defined in the package.

8. removeChars(s string, num int) string: Removes num characters from the beginning and end of the string s.

9. detectOS() string: Detects the operating system and returns its name ("linux" or "windows").

10. errcode(error string): Prints an error message along with an exit code and terminates the program.

11. getid() []byte: Gets the machine ID used for encryption. It returns the machine ID as a byte slice.

12. getidforencl() []byte: Retrieves the machine ID from the "/etc/machine-id" file and generates a valid AES key from it. It returns the AES key as a byte slice.

13. getIDForEncryptionw() (string, error): Retrieves the MAC address of the first non-loopback network interface on a Windows system. It returns the MAC address as a string or an error if it fails.

14. userroot() bool: Checks if the current user is the root user.

15. encryptyaenss(data []byte) (string, error): Encrypts data using AES encryption with a key derived from the machine ID. It returns the encrypted data as a base64-encoded string or an error if encryption fails.

16. decryptyaenss(encrypted string) (string, error): Decrypts data encrypted using AES encryption with a key derived from the machine ID. It returns the decrypted data as a string or an error if decryption fails.

17. listPasswords(passfile string): Reads a password file, decrypts the passwords stored in it, and prints the service and decrypted password pairs.

18. encrypt(data []byte) (string, error): Encrypts data using AES encryption with a key derived from the machine ID. It returns the encrypted data as a base64-encoded string or an error if encryption fails.
