Using '&' character in Reporting Services Encryption Key Password makes restore impossible by pvitt

Using a '&' character within your password results in the following error:

>rskeymgmt.exe -a -f file.snk -p Strong&Password

Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
'Password' is not recognized as an internal or external command, operable program or batch file.

It seems that the “&” character within in the command line ends the commands before it, and starts a new command line for the characters after it. For example, if we set the path of the .snk file to include the “&” character, the same error will occur. However, if we backup/restore the encryption key via the Reporting Services Configuration Manager instead of the rskeymgmt utility, we can specify the “&” character in the password.
