Bug report: "From Base45" cannot decode some result of "To Base45"

[mikecat]

Describe the bug

There is some input that "From Base45" cannot convert back to the original input after encoding via "To Base45".

Instead of successfully decoding, message "Triplet too large" appears.

To Reproduce

From Hex, To Base45, From Base45, To Hex - CyberChef

Example input (first part of deflated data I dealed with):

8d 54 cb 6e c2 30 10 bc fb 2b 72 0c 12 92 b3 4e 02 c1 37 3b 54

Result of "To Base45":

0*HDWPWOO952*XV IETF22UMUF9:6*1

Message from "From Base45":

Triplet too large: '*6:'

Expected behaviour

Results of "To Base45" for any input should be converted back to the original input via "From Base45" with the same Alphabet.

8d 54 cb 6e c2 30 10 bc fb 2b 72 0c 12 92 b3 4e 02 c1 37 3b 54

is encoded to

0*HDWPWOO952*XV IETF22UMUF09:6*1

on

Base45 Encoding - Online Decoder, Encoder, Solver, Translator

This result of encoding is successfully decoded on CyberChef.

It looks like an error in "To Base45": F09:6 in the correct encoding becomes F9:6 (0 is missing) in the CyberChef result.

Simpler example:

00 00

is encoded to 000 on dCode, but encoded to 00 on CyberChef.
