An OLD trick I did in earlier times was to tack on (at beginning or end), a special character(s)... such as "!@#" but only AFTER the encryption, then I could check the raw value coming in...

if left( lcTestVal, 3 ) == "!@#"
  */ Already encrypted via the save of extra string...
else
  lcEncrypt = YourFunction( lcTestVal)
  */ only tack on after encryption to prevent false encryption value
  lcSaveEncrypt = "!@#" + lcEncrypt
endif

if it didn't have the "!@#", then I knew I had to encrypt it... When needed after for decrypting, be sure to likewise, strip it off..

if left( lcTestVal, 3 ) == "!@#"
  */ Already encrypted via the save of extra string...
  lcDecryptBasis = substr( lcTestVal, 4 )
  */ Now, decrypt the lcDecryptBasis field
endif

>I am using vfpencryption.fll in encrypt a user's password and then I am using strconv(password,15) to convert the results so it will store in a database easier. I have run into an issue trying to test if the password is encrypted so I don't try and encrypt it twice. Is there a way to test if a string has been converted?
