StrongKey CryptoEngine (SKCE) 2.0 is a "crypto Swiss Army knife" server to perform cryptographic functions through web services, while freeing application developers to focus on business functionality. Its modules include: - A FIDO Engine to support FIDO U2F key registrations/authentications - An encryption engine to encrypt/decrypt files using AES/TDES keys - Escrowing keys to on-premises key management system (StrongAuth KeyAppliance/SAKA) - Integration to cloud storage services (AWS S3, Azure and Eucalyptus Walrus) - A signing engine to digitally sign documents, code, etc. with FIPS 140-2 HSM support - An LDAP Engine for AD/LDAP integration for authorization decisions SKCE is battle-tested and in production at one of the largest e-commerce companies in the world, protecting more than 50M documents within the business process; see http://bit.ly/14VPYlO for the case study. Download StrongKey CryptoCabinet (SKCC) on this site to see how to use SKCE.

Introduction: This project has been developed to detecting intruder activity in your network according to the existing signature of intrusion attacks,Anomalous behaviour etc... Scope: Government authorities has lot of information about defence,revenue,income tax and many informations. Intrusion Detection System will certainly minimize the unauthorized access and take immediate response to stop such illegal works. MNCs manages their whole information system using application software over their network.It will be helpful to monitor all the activity in the network. Planning: >Studying network protocols and prototypes >Studying similar kind of existing technologies >Writing of Code in Java using jpcap library >Deployment and testing over anetwork Online References: >http://netresearch.ics.uci.edu/kfujii/Jpcap/doc/ >http://docs.oracle.com/javase/tutorial/ >http://docs.oracle.com/javase/7/docs/api/

There is a reason this project holds no code. chaOS41 is a cryptocurrency with reality binding. A given value of money was paid for a surface area the size of a flower pot. It was out of proportion. The chaoOS41 currency corrects that. It binds its value to reality. Its unit value is a ratio between money and land area.. When that ratio normalizes, the currency becomes available to the public. 1 more developer is wanted. For that you need inside access, which means the access protocol is made public now. It is also the open-source cryptographic protocol. Type in a formatted string as "beacon" and a number. Repeat. When the identical string is produced, prepare. When the identical string repeats, a name is added. This signals that the next line of text you type, is registered. Hint: include a URL.End of protocol. Valid beacon digits are 250, 1024, 2048, 4096, 8192, 16384, 32768 and up.
