TPad v1.4 SiCoDe's Notepad Program
CODER v1.0 Str <-> List conversion
SiCoDe Security Suite (SiSecure) is a compilation of SiCoDe's security programs, all included in one collection. Included are programs to encrypt and decrypt String (Str) and Picture (Pic) files as well as to convert strings to lists and back again.
SiCoDe SiPHER is an advanced Str encryption
and decryption tool. Using a key built into the program (and
user-customisable) it substitutes letters in a string for another letter
in the key. However this means it will lose any special characters
(such as Theta) that you have in your text. Strings can be encrypted more
than once, and this will increase the security of the string.
As of v1.1 you can specify your own key.
Also encryption progress is now shown as a percentage, so larger strings
may not show any sign of working.
SiCoDe SiMAGE is an advanced Pic encryption and decryption tool. It generates a 94 character long key which is used to determine whether to change a pixel at different points in an image. While this is slow, it will render an image totally unrecognisable. HOWEVER do not encrypt an image more than once otherwise it will become irrecoverable. The key is held in the form of a list (lPIC) which must be present to decrypt the image.
While TPad is not directly a security tool, it is useful for setting strings which you can encrypt using SiPHER. It includes features like "page viewing", SOS compatibility and Str1 memory indicator and is only 729 bytes.
CODER can be used to save your encrypted strings as lists, allowing you to have effecively double the number of strings. CODER is also WritePad (SiCoDe's Advanced String Editor) compatible.
SiPHER has one known bug - when encrypting some larger strings, after encryption an error message will appear. If this happens, do not worry, your string is still encrypted. Just ignore the message. As we are not sure what causes this message only to appear on some strings, and it does no real damage, we are releasing the program anyway.
SiCoDe Security Suite has no other known bugs.
