	History of Major Improvements
	Version # Date	Description
	1.09 Aug 7/2024	Added the Data Recovery module to: Setup your personal set of security questions which will be used to recover your master password. Record all the symmetric secret keys you ever used to encrypt some data. If you have forgotten or lost a secret key, all the past ones can be tried to see which one can decrypt the data. This process will take less time if you know the approximate date the data was encrypted. Record the creation key which was used to create all of the public/private keys you ever used. A process similar to that for symmetric secret keys can recover encrypted data. Note: the Data Recovery module is a separate add-on to the Data Krypter.
	1.07 July 2/2024	Companies can buy a discounted multi-user license so that all of their employees can use the Data Krypter.
	1.06 June 17/2024	User is forced to pick a strong master password, secret key and creation key. i.e. 9 or more characters, including at least 1 upper case letter, 1 lower case letter, 1 digit and 1 symbol.
	1.05 May 28/2024	When encrypting a file/folder you have two choices of which folder to copy it to: a) the same folder as the unencrypted copy b) a different folder When decrypting a file/folder you have three choices of which folder to copy it to: a) the same folder as the encrypted copy b) the original folder where the unencrypted copy came from c) a different folder
	1.04 May 3/2024	When encrypting a file/folder it can be given a random name, to further hide it. An encrypted file can also be renamed later and when decrypted the original name will be recovered. (The original name is saved in the encrypted file.) e.g. Usually when a file such as Letter.doc is encrypted it is given the name Letter_doc.dke, but it could be renamed to a random name such as J45RX12.dke and when decrypted will have the original name: Letter.doc. The user guide explains how to protect your computer from key loggers. (Which are a type of malware that record everything you type on your keyboard including your master password or secret keys.)
	1.03 Apr 12/2024	After an encrypted file is viewed without any changes and is closed, the original encrypted copy will be unchanged. i.e. the encrypted copy will be updated only if the file was changed.
	1.02 Apr 2/2024	An encrypted file can be viewed/edited then when the view/edit window is closed, it will be encrypted back to the same location. The file can be opened from inside the Data Krypter or by double-clicking it. To keep your data secure, the file being viewed/edited will be automatically be closed after the time-out period you set. Any file/folder that is encrypted can be copied to a backup folder or to the cloud. (i.e. by saving it to Dropbox, Google Drive, OneDrive, etc.)
	1.01 Dec 15/2023	Improve the encrypting of the master password, by adding 'salt' characters, so an attacker does not know its length.
	1.00 Nov 14/2023	First version
