I wrote some basic functions to convert a string to hexadecimal, to convert hexadecimal to a string. Also a function to dump a string to it’s component bytes, listing on each line, the character, it’s ASCII code in hexadecimal, and ASCII code in decimal. Example output:

PS C:\> HexToString "4861726B212053686F77206D6520616E206578616D706C653F3F" Hark! Show me an example?? |

PS C:\> HexDump "So how is this?" S 0x53 83 o 0x6F 111 0x20 32 h 0x68 104 o 0x6F 111 w 0x77 119 0x20 32 i 0x69 105 s 0x73 115 0x20 32 t 0x74 116 h 0x68 104 i 0x69 105 s 0x73 115 ? 0x3F 63 |
The code. They are basic functions, not Advanced Functions, so nothing fancy.
