	SSL certificate verification

Solution If you encounter a problem during SSL certificate installation in IceWarp Mail Server one of the reason can be corrupted certificate file. IceWarp Mail Server works with .pem file format only. You should treat the file very carefully - even one whitespace character can cause the Server will reject the file as corrupted.

You can use OpenSSL to verify the file consistency. OpenSSL is standard tool in Unix/Linux environment. Windows version is available as well. At command line run the OpenSSL with following parameters to verify your SSL certificate file:

openssl rsa -in cert.pem -text

OpenSSL tool will print out details about certificate file. If the file is corrupted (for example it contains additional whitespace characters) it will tell you in which part of the file is a problem. For example SSL certificate file contains whitespace character in Private Key section - OpenSSL will return error message:

unable to load Private Key
