You could write a load-prop function that replaces all non-alphanumeric characters in the variable names with underscore like this:

Code:
#!/bin/bash
function load-prop {
 . <(
  awk '
    FNR==NR {
       p=index($0, "=")
       if (!p) next
       VAR=substr($0,1,p-1)
       NEW=VAR
       while (match(NEW, "[^_A-Za-z0-9]"))
          NEW=substr(NEW, 0, RSTART - 1) "_" substr(NEW, RSTART + 1)
       if(NEW != VAR) repl[VAR]=NEW
       next
    }
    {
       for(rep in repl)
          gsub(rep, repl[rep], $0)
    }
    1
' $1 $1)
}

load-prop ./myfile.props

echo "SITEAURL2 is $siteAURL2"
echo "test.enc is $test_enc"

Output:
Code:
SITEAURL2 is http:/siteAhostname/pageNameA/blabla?v1=32
test.enc is AFSAF!+==


Edit:

Just noticed that test.enc has had the string $fsafasf incorrectly expanded by the shell.
Single quotes could avoid this issue, easy if you can update your prop file(s).

The awk script could adjust for this automatically, but it needs to identify when this is needed

If all variables use the ${} format then $ characters without a following { could be used to trigger the quoting eg:
Code:
test_enc='AFSAF!$fsafasf+=='

You may also have issues with spaces within the variable values.
