AlphaPeeler Professional 1.1 - Version 1.1 AlphaPeeler is a powerful tool for learningCryptography and is used as educational tool at thefaculty of Computer Engineering, SSUET. Students caneasily learn frequency analysis and ciphers likeMonoalphabetic substitution, Caesar and Transposition.AlphaPeeler Professional 1.1 (Dr. William StalingsEdition - powered by crypto++ 4.1) also includes DES,Gzip/Gunzip, MD5, SHA-1, SHA-256, RIPEMD-16, RSA keygeneration, RSA crypto, RSA signature & validation, andgeneration of secret share files. AlphaPeeler 1.0 wasdeveloped at Department of Computer Engineering, SirSyed University of Engineering & Technology - Karachi(Pakistan). You can contact AlphaPeeler developmentgroup (alphapeeler@bigfoot.com) , for you softwaredevelopment, security and ecommerce requirements.Copyright © 1997-2009. New stuff, changes and buf fixes in AlphaPeeler Pro.1.1 (Dr. William Stalings Edition) are:1) AlphaPeeler text editor’s default font changed topoint 12, Aril.This increases the visibility of textthat is displayed inside AlphaPeeler MDI windows.2) In DES crypto, the DES-CBC encryption routine wasnot adding the "\r\n" character at the end of file,which was not allowing AlphaPeeler’s editor to loadfile in editor. This bug has been fixed in release 1.1.3) In RSA crypto, the encryption routine was not addingthe "\r\n" character at the end of file, which was notallowing AlphaPeeler’s editor to load file in editor.This bug has been fixed in release 1.1.4) End of line character ("\r\n") is still not added inthe RSA sign routine after signing the file, but theglobal file read routine in the AlphaPeeler’s editornow handles this bug.Line 90 of AlphaPeelerDoc.cpp :CAlphaPeelerDoc::OnOpenDocument5) spelling mistake removed : seceret share files ->secret share files6) In substitution decryption process, the mapping ofalphabet D was incorrect which was not allowing theletter D to replace with alternate choice entered bythe user. This bug is fixed now.
