Frequently Asked Questions

Can I use other encryption algorithms such as RC2, RC4, or Twofish?

Powertech - Products - Encryption
AES encryption is not the only encryption algorithm that provides strong encryption. There are other encryption algorithms that can be used to secure your data. However, AES encryption is the current federal standard, and likely to be the basis for future state and federal regulations. AES encryption is the only algorithm that has a federally supported certification process.

What are encryption algorithms?

ICT Authority - IT - FAQ
Encryption algorithms are mathematical formulas that are used to transform a readable message to a message that can only be read by the intended recipient. In this encryption method the information is encrypted so that only the intended recipient is able to read and transform the message. The message can be intercepted, but it is useless to a person, who cannot decrypt it. Encryption and decryption of the information requires, in addition to the encryption algorithm, a key.

Q11. Are you using proprietary encryption algorithms?

Application Security Inc. - DbEncrypt - Database Encryption ...
We are not inventing new encryption algorithms for use in this product. DbEncrypt supports dozens of industry-standard, royalty-free algorithms including AES (Advanced Encryption Algorithm), DES, RSA, and Twofish. The algorithms we have chosen to use have withstood the tests of time as well as public scrutiny.

What is Twofish?

PGP DH vs. RSA FAQ
Twofish is an AES candidate produced by Schneier, Kelsey, Whiting, Wagner, Hall, Ferguson first presented in [SKWWHF98]. It is included as a separate section in this document because OpenPGP & NAI have decided that Twofish is such a promising cipher that it should be added to PGP prior to the outcome of the AES process [Koc98], [Pri99a]. Twofish is an evolution of the cipher Blowfish. Most changes seem to have been made to meet the AES criteria.

What algorithms does the NameThesaurus use ?

FAQ
The NameThesaurus uses a combination of phonetic and other techniques for name variant identification. All surnames are limited to 27 characters (a-z and " ' "). Double-barrelled names are split into their component parts and treated independently. All accented characters are converted to their closest matching letter (e.g. ?, ?, ? and ? are all mapped to " a ").

Why doesn't FileAssurity offer a choice of encryption algorithms?

FileAssurity - Trouble Shooting - General Product FAQs
Choosing an encryption algorithm is a non-trivial undertaking. The overwhelming number of users want a product that is best of breed, not a product demanding they make choices they don't want to understand. ArticSoft have followed the most up to date guidance given by bodies such as the US National Institute of Science and Technology (NIST) in their recommendation for the Advanced Encryption Standard (AES) chosen to replace the Data Encryption Standard (DES).

What is encryption?

Cypherix Products - Cryptainer LE Frequently Asked Questions
Encryption garbles your data by using irreversible mathematical functions. It is simply the encoding of data so that it cannot be read by anyone who does not know the password that decodes it.

Wakulla Bank: Online Banking: FAQ
Encryption technology ensures that another party cannot access your confidential account information. Encryption is a way to rewrite something in a code, which can be decoded later with the right "key". When you request information about your accounts, the information is sent across the web in an encrypted format. When the information reaches you, it is decoded so that you and no one else can read it.

How does BitWise use encryption and how can I verify it?

BitWise IM - FAQ
The short answer: BitWise uses encryption on all messages and files sent between you and your contacts; this includes whiteboards, shared file lists, and chat rooms. You can verify the encryption by using a packet sniffer on yourself to watch your network traffic. The long answer: Our white paper Introduction to encryption and how BitWise uses encryption explains in detail how BitWise's encryption works and how the encryption protects and benefits you.

What kind of encryption does Cryptainer LE use?

Cypherix Products - Cryptainer LE Frequently Asked Questions
Cryptainer LE runs as a special Windows device driver. It operates on a 128 bit implementation of the Blowfish algorithm in Cipher Block Chaining mode with a block size of 64 bytes. This ensures that data encrypted using Cryptainer LE is impermeable to all known forms of attack. Statistically, it would be impossible to successfully brute-force crack the Cryptainer LE encryption. Blowfish was designed by Bruce Schneier.

What about algorithms?

Curriculum and Instruction Department - Denver Public School...
The word algorithm is a part of your children’s working vocabulary when they use the Everyday Mathematics program. An algorithm is a set of rules or well-defined procedure guaranteed to achieve a certain objective. For example, following the directions for assembling a new toy for your child, using a recipe, and following any procedure are all examples of algorithms. In mathematics, an algorithm is a recipe for computation.
Related Questions

Typically you use a recipient public key to establish a cipher key, and then use the cipher key to encrypt the bulk of the message. The integrity of the message is assured by including a MAC of the message. The authenticity of the sender is assured by a digital signature and some certificates. You could look at something like SSL or S/MIME for an example, although these are not really good starting points for designing a new system.

Which cryptographic algorithms do SSL use?

OWASP Application Security FAQ - OWASP
SSL supports a number of cryptographic algorithms. During the initial "handshaking" phase, it uses the RSA public key algorithm. For encrypting the data with the session key the following algorithms are used - RC2, RC4, IDEA, DES, triple-DES and MD5 message digest algorithm.

What are all those deinterlace algorithms ?

DScaler - Frequently Asked Questions
Yes you can. DScaler is being developped mainly by people using it as an analog source scaler for their projector and they prefer for sure using DScaler from their remote on the sofa rather than from their desk ;-) DScaler is thus filled with keyboard shortcuts for all main options so that you can do everything quickly. We also suggest the use of Girder from Ron Bessems as the application of choice for remote controlling your computer. An export group has been developped. Download it here.

What is the RC4 cipher - and what are it's flaws?

FAQ
RC4 has several security weaknesses - see here. So why should you use it? Well IE6 doesn't have AES for starters. IE7 will have support for it, but in the meantime it is needed for compatibility reasons. Fortunately SSL sessions are relatively short lived, so the security impact is fairly minimal. Its also very small and fast - so for embedded systems that have size/speed requirements, then RC4 is the cipher of choice.

Can I use encryption APIs in V5R3?

Powertech - Products - Encryption
In V5R3 and i5OS IBM introduced new APIs that support Triple DES and AES encryption. These APIs are a starting point for developing a field level encryption strategy. You can think of these APIs as a set of tools and a starting point for creating a security strategy. If you use these APIs you should be aware of the following limitations: The IBM encryption APIs do not support any type of key management. You will need to construct key management routines and be prepared to defend your approach.
