How to Generate a Self-Signed Certificate to Use with GlobalSCAPE Mail Express

  1. Acquire OpenSSL by going to http://www.slproweb.com/products/Win32OpenSSL.html and downloading the following:
    • Win32 - Win32 OpenSSL v1.0.0(x) Light ? “x” should be the most recent version
    • Win32 - Visual C++ 2008 Redistributables

      OR

    • Win64 - Win64 OpenSSL v1.0.0(x) Light ? “x” should be the most recent version
    • Win64 - Visual C++ 2008 Redistributables (x64)
  2. Install the appropriate package from 1.b above
  3. Install the appropriate package from 1.a above
  4. Navigate into the bin subdirectory of the OpenSSL directory (or add it to your Windows Path so it is recognized)
  5. Run the following sets of commands:
  6. openssl genrsa –des3 –out keyname.key 2048

    This will require entering the passphrase for the key twice.

    openssl req -new -key keyname.key -out csrname.csr -subj "/C=country/ST=state/L=city/O=organization/OU=department/CN=fullyqualified.dnsname.net"

    This will require entering the passphrase once.

    openssl x509 -req -days 365 -in csrname.csr -signkey keyname.key -out certname.crt

    This will require entering the passphrase once.

    Run the following command if you want to remove the passphrase from the key:

    openssl rsa –in keyname.key –out keynameclear.key
