New Tool: SimpleEncoder

I needed a 010 Editor script to do ROT-47 encoding. The script I developed supports different types of simple encodings (including ROT-47):

With custom shift encoding, you choose the shift value by providing a number in a second input dialog. This number can be negative to shift the characters to the left in stead of to the right.µ

FYI: I submitted this script to 010 Editor’s repository.

Update: numbers-to-string.py Version 0.0.7

In this update, I added option -T. This is an alternative for option -t (table for number to character conversion). In stead of providing the full table with option -t, now you can provide a partial table with option -T, provided the table is present in the input.

This is often the case in DOSfuscated scripts:

In this example, the table starts with MkBMMM. Hence I use option -T MkBMMM, in stead of option -t with the full table: -t MkBMMMdkGLKIEzzjzlJJanhzSNf7,Y9x@bm(/5Hqo6 +8wri)$;uv{-QtgOUP}C:\VDFW.=y’AsRe0cp

Update: XORSearch Version 1.11.2

This update for XORSearch brings new features and bug fixes.

Starting with this version, XORSearch accepts input from stdin. Use filename – to read data from stdin:

Option -S will print out all strings found using all decoders supported by XORSearch. Strings are sequences of printable characters, ASCII and UNICODE, at least 4 characters long.

As option -S brings many of the functionalities of XORStrings to XORSearch, I’m no longer developing XORStrings.

Last new option is -r. You can use option -r to reverse the file before searching.

I’m also including more compiled versions (look inside the ZIP file).
