How secure is the conventional cryptography option?
The comp.security.pgp FAQAssuming that you are using a good strong random pass phrase, it is actually much stronger than the normal mode of encryption because you have removed RSA which is believed to be the weakest link in the chain. Of course, in this mode, you will need to exchange secret keys ahead of time with each of the recipients using some other secure method of communication, such as an inperson meeting or trusted courier.

Able Encryption Software. Safe Soft Corporation. Frequently ...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.
Related QuestionsDigital Certificate Registration CenterCryptography is the science of enabling secure communications between a sender and one or more recipients. This is achieved by the sender scrambling a message (with a computer program and a secret key) and leaving the recipient to unscramble the message (with the same computer program and a key, which may or may not be the same as the sender's key). The emphasis of cryptography is on data confidentiality, data integrity, sender authentication, and non-repudiation of origin/data accountability.Related Questions

DCSSI FAQCryptography is a science intended to convert unencrypted information or signals into information or signals using secret conventions called keys, such that the information or signals are unintelligible to third parties who are not aware of the secret used to convert the signals, or to perform the reverse operation using hardware or software means designed for this purpose.Related Questions
Digital IdentityCryptography is the science of disguising information through encryption (scrambling) and restoring it to its original form through decryption. It provides similar, but much stronger, security assurances that signatures, paper envelopes and codebooks have always provided.Related Questions

Related QuestionsWhat is conventional memory?
DOS FAQ by Christoph FuchsThe first 640 KB of your RAM are called "conventional memory" under DOS. DOS can only address this first 640 KB of RAM directly, the other part won't be recognized if you don't load a memory manager like himem.sys. Most programs need a special amount of conventional memory to run, so it would be good to have as much free memory as possible within this 640 KB. How can you do this? Well, that's not quite difficult, but it is not fairly easy.

Supermarket chains have huge purchasing power and offer artificially low prices on conventional and even surprising low prices on some organic produce by buying large quantities and distributing them nationally. It's important to understand that local producers cannot always compete price-wise, but make up the difference in so many other ways.
Related QuestionsWhat is encryption and cryptography?
JARING E-MALLEncryption is the transformation of data into a form (a cipher) that is, for most intents and purposes, impossible to read with out the appropriate decoder (a cryptographic key). Its purpose is to ensure privacy by keeping information hidden from anyone for whom it is not intended, even those who have access to the encrypted data. Decryption is the reverse of encryption; it is the transformation of encrypted data back into an intelligible form.

What is symmetric cryptography?
The National Committee for Voting Integrity (NCVI)Encryption uses a mathematical key to provide secrecy. Symmetric cryptography refers to encryption systems that use the same key to encrypt and decrypt.

The comp.security.pgp FAQIt is not secure at all. There are many ways to defeat it. Probably the easiest way is to simply redirect your screen output to a file as follows: pgp [filename] > [diskfile] The "for your eyes" option was not intended as a fail-safe option to prevent plain text files from being generated, but to serve simply as a warning to the person decrypting the file that he probably shouldn't keep a copy of the plain text on his system.

Related QuestionsWhat is secret/symmetric cryptography?
Digital Certificate Registration CenterSecret key (symmetric/conventional) cryptography is a system based on the sender and receiver of a message knowing and using the same secret key to encrypt and decrypt their messages. One weakness of this system is that the sender and receiver must trust some communications channel to transmit the secret key to prevent from disclosure. Example: You use a strongbox to send a valuable gift to your friend, locking it with a key. No one can get to the gift without the key, including your friend.
