Dear All, I'm using Koha227 on windows platform. I'm working on a customization module of patron authentication using Digital Signature. Patron could search books and send requisition to the librarian. At the time of the issue, the patron has to give his/her password. The information regarding the book, patron id etc will be converted into a message digest and using a Digital Signature algorithm, would be stored in the database. In future if the patron denies accepting the book, this will be used to very the patron authentication. So, far I'm not able to install the module required for the implementation of digital signature. Should I go for implementing the Crypt::DSA module?? if so how should this module be installed. thanx Arnab -- View this message in context: http://www.nabble.com/Digital-Signature-Implementation-tf4872852.html#a13943...
