redirect url can't contain newline characters - encrypted query string

[Sue Stoos]

Hello,

I'm currently trying your product and like what I see so far.  However, I am new to Encryption and need to send the string that was generated by the pgp.EncryptString method in a querysting.  I used a key from my client and am not able to use it to decrypt the information I need to send.  The

When I append the encrypted string to the url, I receive the following error:  Error received: System.ArguementException     {"Redirect URI cannot contain newline characters."}

 The encrpted string that I'm trying to send looks similar to:

"-----BEGIN PGP MESSAGE----- Version: BCPG C# v1.7.4114.6378  hQIOA+nqApdgUx5pEAf+LdWa3c4lmoNbZyoJT0BKt+4LQ/6RvY5IvQcOGWN7+hRW sMm7DShFlNPaKcC+NyyOioCRjZoL1mAQrE8dcm9mwn+v91bDRhEiLV29t7+6UldJ BzdHE4QzELMo+NvX8zFAe8228lIrZdvQ77Dex/4W9cKDJA/TWVOobGVWyPx3H+Jb aKJPPBkHkBNnBwcyXZ0MZViDn2x2ltzw9gpcL4HJroTyf1FQf6Q22Q5+uAFdUQcy NsaAq9IBQIX3/CJiLunYmOKX0dMiN3oCn4l0uTtdvHsiNmm/KdVwWA6CJqP85w== =7LiY -----END PGP MESSAGE----- "

 Also, here is my code used to encrypt the string, with some moderaton to not display true data:  The language is VB.net

strLogin as string

strEcpt as string

strlogin ="empid=1122334455" & Today.date & "group=1234" 

 strExpt = pgp.EncryptString(strlogin, keystore, "ID")

response.redirect("https://sitename.com/sso.asp?" & strExpt) - Get error as soon as I hit try to redirect to client page.

 I'm in a time crunch to complete this so any help would be extremely appreciated!!!

Thanks for your time.

Hi Sue,

One possible soluton to this situation can be to encode the encrypted string using the HttpUtility.UrlEncode method.

For example:

response.redirect("https://sitename.com/sso.asp?" & Server.UrlEncode(strExpt))

Of course your recipint MUST decode it before decrypting with UrlDecode.

For more information, please check

For url decode for the old pre-.NET ASP check

http://www.aspnut.com/reference/encoding.asp#urldecode

Please also have in mind that the url is limited by the browser.
