hex2bytes
hex2bytes(s::ASCIIString)
Convert an arbitrarily long hexadecimal string to its binary representation. Returns an Array{UInt8,1}, i.e. an array of bytes.
Examples
julia> hex2bytes("48656c6c6f20576f726c64")
13-element Array{UInt8,1}:
0x48
0x65
0x6c
0x6c
0x6f
0x20
0x57
0x6f
0x72
0x6c
0x64-
Convert hexadecimal string to byte array:
julia> hex2bytes("48656c6c6f20576f726c64") 13-element Array{UInt8,1}: 0x48 0x65 0x6c 0x6c 0x6f 0x20 0x57 0x6f 0x72 0x6c 0x64This example converts the hexadecimal string "48656c6c6f20576f726c64" to an array of bytes.
-
Handle empty string input:
julia> hex2bytes("") 0-element Array{UInt8,1}It correctly handles the case where an empty string is provided as input.
- Convert shorter hexadecimal strings:
julia> hex2bytes("ab12") 2-element Array{UInt8,1}: 0xab 0x12It can convert shorter hexadecimal strings as well.
Common mistake example:
julia> hex2bytes("48656c6c6f20 576f726c64")
ERROR: ArgumentError: Invalid hexadecimal string: contains invalid characters or spacesIn this example, the input string contains invalid characters or spaces, resulting in an ArgumentError. hex2bytes expects a valid hexadecimal string without any spaces or other special characters.
