Required Software for Web Digital Certificates
The browser, in which you use SIGEN-CA web qualified digital certificates, must enable strong encryption, i.e., the usage of 128 bit keys for algorithm RC4 and 2048 bit keys for algorithm RSA.
You may check this either by reading the information about browser or by connecting to the test server and clicking "Connection Data". In the box, which opens, you should find "simmetric cipher: RC4-MD5, 128 bits " or another simmetric cipher with key longer than 56 bits. If not, please install a newer version of a browser, which will enable strong encryption.
