Are there other efforts to find RSA's Secret DES Key?

DESCHALL Project Frequently Asked Questions
Yes. After some other efforts folded, there are three efforts that are major contenders for finding the key. These are... It's noteworthy that we've got the fastest key search rate by far. Despite the fact that we seem to have fewer clients than another, the ones we have are extremely fast. As a result, we've nearly moved into first place for amount of keyspace searched, and we have been holding on to first place for keyspace search rate for quite some time.

What is the secret key?

CFXHosting - Advanced Hosting Solutions for Macromedia Devel...
The secret key is a special string of text that encrypts all the data that is stored on the server. This secret key can be changed at anytime between backups and restores. If the key is forgotten or lost, the backup server administrator may not be able to recover the data on the server so make sure you keep this information in a safe place.

c) What is secret key cryptography?

Digital Signature India
Secret-key cryptography is sometimes referred to as symmetric cryptography. It is the more traditional form of cryptography, in which a single key can be used to encrypt and decrypt a message. Secret-key cryptography not only deals with encryption, but it also deals with authentication.

How do I negotiate secret key with another user?

SILC Secure Internet Live Conferencing
It is important to negotiate secret keys if you cannot trust the servers and the network you are using. By negotiating a key with the user you want to talk to assures that no one except you and your friend is able to encrypt and decrypt the messages. The secret key negotiation is done with the KEY command. Here is an example of how to negotiate keys for securing private messages. By giving command: /KEY MSG john agreement 192.168.2.

What is RSA?

eBusiness Resource - Introduction to eBusiness - Any Questio...
With conventional encryption systems, such as used by submarines during the last world war, the submarine had to leave base with a codebook, which matched the codebook back at HQ. Moving codebooks around the place is troublesome and potentially open to security risks but for centuries was the method used for secure military diplomatic, inter-bank etc communications.

Are the newer public key methods better than RSA?

Diffie-Hellman (DH) is actually older and simpler than RSA, and along with DSA it can be used for all the things that RSA is commonly used for. The differences are minor and technical. Elliptic curve cryptosystems (ECC) have the advantage of shorter public keys. The best attacks on ECC are exponential in the keysize, while the attacks on RSA and DH/DSA are sub-exponential, so ECC will become more attractive after a few more years of Moore's law.

My secret key ring has been stolen or lost, what do I do?

The comp.security.pgp FAQ
Assuming that you selected a good solid random pass phrase to encrypt your secret key ring, you are probably still safe. It takes two parts to decrypt a message, the secret key ring, and its pass phrase. The secret key is encrypted with the passphrase before it is stored in the secret keyring. Assuming you have a backup copy of your secret key ring, you should generate a key revocation certificate and upload the revocation to one of the public key servers.

Can there be unquestioned assurance that the key remains secret?

The National Committee for Voting Integrity (NCVI)
Of course not. Keys are either known by people, or stored in devices that people have access to. No matter what protocols and procedures are used, people are always prone to making mistakes The most we can do is minimize our reliance on secrets and then build procedural safeguards around the few secrets that we depend on people to keep.

I still have my secret key, but lost my public key. What can I do?

GnuPG Frequently Asked Questions - GnuPG.org
All OpenPGP secret keys have a copy of the public key inside them, and in a worst-case scenario, you can create yourself a new public key using the secret key. A tool to convert a secret key into a public one has been included (it's actually a new option for gpgsplit) and is available with GnuPG versions 1.2.1 or later (or can be found in CVS). It works like this: One should first try to export the secret key and convert just this one. Using the entire secret keyring should work too.

How do I indicate that my key is invalid when I don't have the secret key anymore?

The comp.security.pgp FAQ
This is a very tricky situation, and should be avoided at all costs. The easiest way is to prepare a key revocation certificate (See 7.3 for details on how to do this) before you need it, so you can always revoke the key, even without the secret key. Alternatively, you can use a binary editor to change one of the user IDs on your public key to read "Key invalid; use key 0x12345678" or something to that effect.

Public key vs. secret key: which cryptography system is better?

Digital Certificate Registration Center
A combination of both. The action of encrypting information with public-key cryptography is significantly slower than encrypting with a secret key. However the drawback of the secret-key system is that, secret keys must be transmitted either manually or through a communication channel, and there may be a chance that others can discover the secret keys during transmission. This is not a problem with public-key cryptography, as private keys never need to be transmitted or revealed to anyone.

What is DES?

Untitled Page
DES (diethylstilbestrol) is a synthetic form of estrogen, a female hormone. It was prescribed between 1940 and 1971 to help women with certain complications of pregnancy. Use of DES declined in the 1960s after studies showed that it is not effective in preventing pregnancy complications. When given during the first 5 months of a pregnancy, DES can interfere with the development of the reproductive system in a fetus.

I can't delete my secret key because the public key disappeared. What can I do?

GnuPG Frequently Asked Questions - GnuPG.org
To select a key a search is always done on the public keyring, therefore it is not possible to select a secret key without having the public key. Normally it should never happen that the public key got lost but the secret key is still available.

If my secret key ring is stolen, can my messages be read?

The comp.security.pgp FAQ
No, not unless they have also stolen your secret pass phrase or you foolishly put it in plaintext on the same disk (see How can I give my passphrase to the commandline PGP automatically?), or if your pass phrase is susceptible to a brute-force attack. Neither part is useful without the other. You should, however, revoke that key and generate a fresh key pair using a different pass phrase just to be sure.

When you change the secret key used, the previous key and all other keys for that matter, are also encrypted using this new key. This way, you only need to remember the most recent key to restore both new and old data.
