EncryptVar specifies the key to use to encrypt variables that are sent as part of starting point URLs. Normally, variables authorized by AllowVars are sent unchanged. EncryptVar changes this behavior by specifying an encryption key that is used to encrypt variable values before they are sent. The primary purpose for this directive is to support encryption of the username that is sent during authentication to Ebook Library.

EncryptVar is a repeatable position-dependent config.txt directive.
