Answers to Frequently Asked Questions about DeltaCrypt Encryption Software: Encryption in General DeltaCrypt Applications--Components and Characteristics DeltaCrypt Applications--Practical Questions Everyone can benefit from encryption software. Everyone, from individuals to corporations, wants be reassured that their confidential information remains confidential. Public key encryption protection can provide that reassurance. Cryptography is the art and science of keeping files and messages secure. It works by mathematically transforming plaintext messages or files into a ciphertext, a process known as encryption. Public Key cryptography is an encryption method that uses two different but related keys: a public key which is used for encryption and the secret key (password) used to decrypt the data. It is best suited for the storage and/or exchange of private or confidential data between two or more parties. DeltaCrypt Encryption Software generates a 1024-character key chosen randomly from all of the 256 ASCII codes available, thus producing a very strong encryption. DeltaCrypt uses a 1024-bit strength RSA public key and a 1024-bit strength RSA private key in its Public Key File Encryption applications. DeltaCrypt Public Key File Encryption Software offers a public key with a name that cannot be altered or modified, because any change makes it invalid. In fact, identification elements are integrated into the public key function. This unique feature ensures that a public key transmitted by a third party for encryption is the exact one intended for the user. Therefore, if the user receives an altered public key with a name similar to the one intended for him (i.e. to mislead him) and uses that key to encrypt confidential information, the system will reject the key and will give an error message. The Identification Number consists of 9 characters that are found in the « About » of the « Help» section of the encryption software. It is used to identify your computer for registration purposes. The Serial Number consists of 13 characters. It is sent to you via email once you have purchased your encryption software application. Once you receive your Serial number you must enter the number in the space provided in the « About » of the « Help» section of your software Demo in order to unlock it Sender Authentication is one of the objectives of cryptography: Typically, it is the assurance that a message was sent by the purported author. By creating a DeltaCrypt Digital Signature for a document, encrypted or not, it assures the document's recipents that it truly originates from the Sender and remains unchanged. DeltaCrypt Encryption Software can be instructed to automatically and randomly generate a 1024-character password from any file or files in a folder that has been selected by the user. The folder can reside on a hard drive, diskette or USB key (as defined by the user) and can contain up to 192 files in any file format (text, programs, spreadsheets, zips, etc.). This is an alternate way to achieve a high level of security without the need to use and remember lengthy manual passwords. Document Integrity is assurance that a document has not been modified during transmission. It also is one of the key objectives of cryptography, i.e. proof that information is what it appears to be: uncorrupted (unchanged) information from the source. A digital signature is a signature in digital format which permits you to detect whether the message has been altered in transit. It is a value that acts like a digital thumbprint. More precisely, it is the hash value of an electronic document which provides for its authentication. The DeltaCrypt application appends a digital signatures to its public key files and to encryptions. Unencrypted files can also be signed so that, if they are changed, the signature file provides an indication that the original is no longer the same. Because the signature file also indicates the name of the public key being used, it also permits users to identify who created the signature. Your source data can come from any media that you can read and write to: hard disk, floppy, CD-ROM, flash memory, USB or Firewire portable drives, etc. With DeltaCrypt USB Protection you also benefit from total mobility, as it runs on any Windows computer, directly from the USB Key. Yes. All file suffixes are accepted. No distinction is made between one file type and another, since all reads and writes are made in binary mode. A single encrypted file can contain encryptions from text, .jpg, .exe, .doc, .zip and/or anything else. Instant messages can be encrypted quite easily from the DeltaCrypt icon in the tool tray. Just select the Email and Text option in the menu. See the User's Manual for more details. Yes, most of DeltaCrypt commercial applications can run in Command Line. To learn more, write us at Contact Us. There is no limit to the size of files nor to the total number of files that may be encrypted at one time. Changing your Windows version will prevent you from using your encryption software application. You must then re-register your application software for free, using the same email address as the one originally used to purchase the software. A new serial number will be emailed to you immediately, and can then be entered in the « About » section of the « Help » menu. Please copy the file install.log to C:\Program Files\DeltaCrypt and uninstall the software again. |
