Re-Encode a String (Hex, Base64, URL, etc)

Demonstrates how to convert from one encoding to another. For example: base64 to hex, URL to base64, base64 to quoted-printable, etc.

Note: The ReEncode method is unreleased at the time of this writing (08-April-2008) The next major Chilkat Crypt2 release after this date will include the ReEncode method.

crypt = Chilkat::CkCrypt2.new()

#  Any string argument automatically begins the 30-day trial.
success = crypt.UnlockComponent("30-day trial")
if (success != true)
    print "Crypt component unlock failed" + "\n"
    exit
end

hexStr = "41424344E0E1E2E3"

fromEncoding = "hex"
toEncoding = "base64"

#  Convert from hex to base64
base64 = crypt.reEncode(hexStr,fromEncoding,toEncoding)
print base64 + "\n";

#  Now convert from base64 to quoted-printable:
fromEncoding = "base64"
toEncoding = "quoted-printable"
qp = crypt.reEncode(base64,fromEncoding,toEncoding)
print qp + "\n";

#  Now convert from quoted-printable to URL:
fromEncoding = "quoted-printable"
toEncoding = "url"
urlEnc = crypt.reEncode(qp,fromEncoding,toEncoding)
print urlEnc + "\n";

#  Now convert from URL back to hex:
fromEncoding = "url"
toEncoding = "hex"
hexStr = crypt.reEncode(urlEnc,fromEncoding,toEncoding)
print hexStr + "\n";

#  The output of this program is:
#  QUJDRODh4uM=
#  ABCD=E0=E1=E2=E3
#  ABCD%E0%E1%E2%E3
