For various reasons I need this module and so I tried to make it happen. I do not think I fully respect the characteristics of conversion, but it works I'm trying to make the decoder, but it seems more complicated because I have to shift the binary data, to be honest I can not simple. 😝

Then try to create a md5 if I'll be able to. 😊

If someone has already created these modules, it would be nice to give him a look?

Edit:removed file...New OSM Complete - Encoder - Decoder in next post!!!

hey nix sorry for this noob question 😊 but whats the use for this?

I am using it for example with the Windows Telnet to send email. and my ISP requires a connection from authorized user and password, the protocol use an encoder at base 64.

ah okay thx 😉

And here we are successful, since both modules in the OSM. Enjoy 😈

Must have been hard work, kudos! SM is IMO not really the right system for these tasks. The interwebs are full of free implementations in C, C++, Javascript, Java, Python, Lisp,...implementations of Base64, MD5 algorithms.

awesome DWB 🙂

w/o going deeper into it a little background question: Which max length should/can i use => where to split a big string?!

Cheers, Walter

The base64 module I created, it can easily be modified for different needs, it could also convert all characters, just remove the filter during encodiing or add a filter to parse the MIME specification, actually a MIME base64 string does not exceed 76 characters. But used for many purposes there is no limit to the string to create, I also added the characters space and return, so the string is already divided as a arrary. However, just proceed to split a string of 4 base64 characters at a time.

Thanks DWB,

now i have 2 build an ASCII Filter for the NUL,STX,DLE,ETX,FS, and SUB etc. signs 😮 in my decoded source... dunno if i have time 4 that 😉

A few rules keep this a friendly place. You agree to them once.

    Open it in SynthMaker?

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
