$encode(&bin,bc,key) * Line too long #261871 05/12/17 07:22 AM

The binary contents do not appear to matter, nor does choice of padding or salt/iv switches. Does not happen with the 'e' switch nor for plaintext defined with text or %variables. Perhaps related to the same error message mentioned in versions.txt for v7.44 To reproduce, load this code then type: /encode_test Code: alias encode_test { echo -a $ $+ 1 is optional ascii number 0-255 var %N 1 \| var %chr $iif($1 isnum 0-255,$v1,49) while (%N isnum 1-17) { bset -c &bin 1 $str( %chr $+ $chr(32),%N) noop $encode(&bin,bc,key) echo 4 -a Length %N encoded as $bvar(&bin,1-).text noop $decode(&bin,bc,key) echo 2 -a Length %N decoded as length $bvar(&bin,0) $+ : $bvar(&bin,1-).text goto label :error echo 3 -a error for length N= %N : $error $bvar(&bin,1-).text reseterror :label inc %N } return }

The example used the default u switch, but when switches for $encode and $decode change from bc to bcm, the error at binary lengths 5-6 disappears, but the errors for the other lengths 1-4,8-10,16 remain. When changing switches to be bca for Base32, the series of lengths affected by the bug expands to: 1-20,24-28,32-36,40,48. Update2: I was incorrect when I said the IV/Salt switches didn't matter. Switches 'bcr' and bcs with Salt had the bug in the same lengths, but switches 'bci' with IV didn't have the bug regardless of u/m/a encoding. Last edited by maroon; 05/12/17 05:04 PM.
