##from_bit / to_bit

Converts a byte string to a bitfield string.

• 0, O and o maps to the same value
• 1, I, i, L and l maps to the same value

basexx.to_bit( "ACDC" ) --> 01000001010000110100010001000011
basexx.from_bit( "01000001010000110100010001000011" ) --> ACDC
basexx.from_bit( "o1ooooo1o1oooo11" ) --> AC
basexx.from_bit( "OioooooiOiooooii" ) --> AC

##from_hex / to_hex

Converts a byte string to a uppercase hex data string.

basexx.to_hex( "Hello world!" ) --> 48656C6C6F20776F726C6421
basexx.from_hex( "48656C6C6F20776F726C6421" ) --> Hello world!
basexx.from_hex( "48656c6c6f20776f726c6421" ) --> Hello world!

##from_base32 / to_base32

Converts a byte string to a base32(rfc3548) uppercase data string.

• It's case insensitive

basexx.to_base32( "chunky bacon!" ) --> MNUHK3TLPEQGEYLDN5XCC===
basexx.from_base32( "MNUHK3TLPEQGEYLDN5XCC===" ) --> chunky bacon!

##from_crockford / to_crockford

Converts a byte string to a base32(crockford) uppercase data string. The optional check value is not implemented.

• It's case insensitive
• 1, I, i, L and l maps to the same value
• 0, O and o maps to the same value
• U, u, V and v maps to the same value (not part of the official description)

string.lower( basexx.to_crockford( "Hello World" ) ) --> 91jprv3f41bpywkccg
basexx.from_crockford( "axqqeb10d5u20wk5c5p6ry90exqq4uvk44" ) --> Wow, it really works!

##from_base64 / to_base64

Converts a byte string to a base64 data string.

basexx.to_base64( "Man") --> TWFu
basexx.from_base64( "TWFu" ) --> Man
