LMAO! Hilarious!!! Your nips got hard! OMG, I broke out laughing when I read that. You definitely have some mad awesome going on Den.
Thanks for the laugh and thanks for playing with this (you too Leigh), I'm out of ideas and its a bit beyond my comfort zone.. FYI, the original author of that Delphi component is nowhere to be found...

Maybe seeing the modulus and exponent parts will help. I'm thinking you are right in guessing that the base64 routine isn't a "normal" base64 routine. The raw data seems to work: var exponent = createObject("java","java.math.BigInteger").init("00000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000C355",16); var modulus = createObject("java","java.math.BigInteger").init("00000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000BFDF38C9703C07CB68 77A41C4B05F5E03EAFC6579F2263CF686289C13B96CCFE9587F5C9FF2D8787A784D0DD8EE1B7 9CD96BB969611E0E42603EB6E4A23CBE3D",16); var pubKeySpec = createObject("java", "java.security.spec.RSAPublicKeySpec").init(modulus,exponent); var factory = createObject("java","java.security.KeyFactory").getInstance("RSA"); var keyInstance = factory.generatePublic(pubKeySpec); But no matter how I played around with it, converting the original "base64" encoded string didn't come anywhere near that-- OMG! I had a thought while typing this, and I think I had a revelation. Remember how the docs mention things being a byte shorter to "speed things up"? Yeah. I just tried dumping the b64 stuff using sun.misc.BASE64Decoder, as a bit of a sanity check, and I'll be damned if the string wasn't almost what it should be. My nips got hard. By adding a 0, both CF and Sun reported the same results! Ex: <cfdump var="#binaryEncode(binaryDecode('++11Ik','base64'),'base64')#" label="orig"> string ++11Ig== <cfdump var="#binaryEncode(binaryDecode('++11Ik0','base64'),'base64')#" label="wazero"> string ++11Ik0= Closer, neh? I can freaking smell victory! I gotta switch gears, but I figured I'd toss this out there, even though it pains me to be so close (theoretically) and not to be able to say "SOLVED!". If I was a selfish person, I'd wait till I figured it out myself, and post the solution. I'm a team player though. The goal isn't personal awesomeness, or whatever. Plus, I'm mad awesome already... ;) :Den -- Sin is geographical.
