What public key algorithms SILC support?
SILC Secure Internet Live ConferencingThe required public key algorithm is RSA, but optional support is for DSS. The RSA algorithm in SILC supports PKCS#1 standard. During the key exchange protocol also Diffie-Hellman public key algorithm is used to exchange keys. The Diffie-Hellman in SILC supports PKCS#3 standard. Adding support for other algorithms like El Gamal is possible by negotiating them in SILC key exchange. PGP keys, or as they are officially called OpenPGP certificates are supported in SILC protocol.
Related QuestionsWhat other algorithms SILC support?
SILC Secure Internet Live ConferencingThe AES is the only required algorithm. The protocol specification also lists optional algorithms like Twofish, CAST, etc., and you can negotiate other algorithms as well during the SILC key exchange protocol, if needed.
Related QuestionsWhat are the algorithms for a public key?
ICT Authority - IT - FAQThe algorithms of a public key are encryption algorithms that require two keys: a public and a private key. When one of these keys is used to encrypt the message only the other key is able decrypt it. The private key must be kept secret. The public key may be published, for instance, in a public directory. The public key can be used to verify the message that has been signed with a secret key or to encrypt a message that can only be decrypted with the private key.
Related QuestionsShould I verify all other public keys in SILC?
SILC Secure Internet Live ConferencingDefinitely yes. You can receive public keys when you negotiate for example private message key with some other client, and you must verify the key before accepting it. Reason are same as in previous answer.
Related QuestionsWhat encryption modes SILC support?
SILC Secure Internet Live ConferencingThe required encryption mode currently is CBC with inter-packet chaining. The specification recommends implementations to use CTR mode as well, and defines randomized CBC (with random IV's) as optional mode. It is also possible to negotiate other modes during SILC key exchange protocol, if needed. We have also looked into so called authenticated encryption modes that NIST are currently considering. More information will follow later.
Related QuestionsWhat hash functions SILC support?
SILC Secure Internet Live ConferencingThe required hash function is SHA-1, but also the MD5 is added to the specification as optional hash function. The SHA-1 is also the required hash function when used as part of HMAC to provide integrity protection for encrypted packets.

Related QuestionsSo SILC can be used with other keys too instead of just SILC public keys?
SILC Secure Internet Live ConferencingYes, that's the purpose of having support for other public keys and certificates. The implementation most likely still wants to create you a SILC key pair, but if you have for example PGP key pair that would be the one you are using in SILC.
Related QuestionsWhat kind of presence modes SILC support?
SILC Secure Internet Live ConferencingBy presence we mean indication of presence in the network, and SILC supports several different kinds of presence modes. They can be changed with the UMODE command which changes your user mode in the network. Currently there are the following modes for presence: GONE (I'm away), INDISPOSED (I cannot be here), BUSY (I'm busy, don't bother me), PAGE (page me if you want to talk), and HYPER (I'm hyper active, talk to me). When mode is not set it means you are present in the network.
Related QuestionsWhere do I find my public key?
WonderCrypt - FAQIf you created your key pair using WonderCrypt's "Create New Private Key and Public Key with CSR" option then you can find your public key in the sub-folder "Certificates". Public key certificate files also called Digital Certificate have ".cer" extension. If you created your key pair using browser: Internet Explorer: Then you will have to export your public key from the browser using the browser's "Tools", "Internet Options", "Content", then "Certificates" option.
Related QuestionsVeridis Open PGPYou can find the public key of someone else by sending him an email asking him to send you his/her public key. Or you can search a public key server for a key. To do that, choose "Search..." from the "Keyserver" menu and type the name of the person you want to find the public key. It is highly recommended to verify that this key belongs the right person. The easiest way to do that is to ask the key id of the key by phone.Related Questions
DCSSI FAQA distinction is made between two types of cryptography, namely, firstly symmetric cryptography called secret key cryptography, and, secondly, asymmetric cryptography or public key cryptography. The principle of secret key cryptography is to use a single secret or a single key to encrypt and decrypt information. Public key cryptography uses different keys in transmission and in reception.Related Questions
Who is behind the SILC?
SILC Secure Internet Live ConferencingThe SILC was developed by Pekka Riikonen in Finland. He also started the SILC project that now coordinates the SILC development. He has worked for years in the field of security, for example several years at the SSH Communications Security Corporation as Chief Engineer with responsibilities in IPSEC core development. The SILC Project consists of several volunteers who maintain the SILC Network, its routers and servers. Volunteers who provide the silcnet.

Related QuestionsWhat is the purpose of the SILC key exchange (SKE) protocol?
SILC Secure Internet Live ConferencingThe primary purpose of the SILC key exchange protocol is to create session key for protecting the traffic between the client and the server. It is executed always when client connects to the server. It can also be used to create other key material for other sessions, like file transfer session. The SKE use Diffie-Hellman for key exchange algorithm, and supports digital signatures and mutual authentication.
Related QuestionsWhat 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 QuestionsTypically 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.Related Questions

Related QuestionsI have created my private key and public key. How do I distribute my public key to others?
WonderCrypt - FAQIf you are an organisation, you can create an address book that contains public keys of all users and distribute the address book itself so that individual users need not distribute individually. WonderCrypt provides an easy to use export / import interface for this task. Whenever you send a signed mail or file to anyone, your public key automatically gets attached to your signed document. The recipient thus receives your public key and can install it to use it.
