In bash, the single quote mark (') and the double quote mark (") are treated differently. Special characters such as dollar sign ($) and  reverse solidus (\) are interpreted in strings contained within double quotes; they aren't in strings contained within single quotes.

Examples:

Code:

pi@moodelr:~ $ wpa_passphrase "$MyFavoriteFootie$" "the $illy name of the captain"
network={
    ssid="$"
    #psk="the  name of the captain"
    psk=a298bf7833845d0fe2eb1bacc9b8c71b2666c803f427a1c22c28fe57613227df
}
pi@moodelr:~ $ wpa_passphrase '$MyFavoriteFootie$' 'the $illy name of the captain'
network={
    ssid="$MyFavoriteFootie$"
    #psk="the $illy name of the captain"
    psk=678bdc6bb2e32a5842c5539da7eebae1732ad8bcde202d3040dab4b65e77b7f4

Note that the reverse solidus can be used to prevent the interpretation of the following character when contained within double quotes:

Code:

pi@moodelr:~ $ wpa_passphrase "\$MyFavoriteFootie\$" "the \$illy name of the captain"
network={
    ssid="$MyFavoriteFootie$"
    #psk="the $illy name of the captain"
    psk=678bdc6bb2e32a5842c5539da7eebae1732ad8bcde202d3040dab4b65e77b7f4
