DocKimbel: 22-Sep-2012 | Marco: besides coding in Red/System, I don't see what you could do currently to speed it up. Here are some ideas for the additional coding that will need to be done: You can write in Red/System some of the non-trivial natives, like e.g. set natives: sort, union, intersect, unique, difference. Other natives or support code we will need are codecs for: - compression supporting these algorithms: deflate, lzo - cryptography: MD5, SHA-1, AES, ...(all the required ones for SSH and SSL support) You can port C code to Red/System, there are tons of available C source code, you just have to make it right (crypto requires accurate coding, implementations need to be deeply tested for flaws). | |

Robert: 27-Jan-2013 | New Android release: URL : http://development.saphirion.com/experimental/ Direct URL : http://development.saphirion.com/experimental/r3-droid.apk Changes: -added DH and AES 128/256 encryption -rewritten console syncing code -TLS scheme improvements -fixed runtime stack size issue -fixed FP math using dtoa() (thanks to Ladislav!) -fixed shared lib unloading issue -fixed "exit on script error" bug -minor app handling tweaks Please give it a try and have fun. | |

PeterWood: 16-Apr-2012 | This is probably because there is no 512-bit AES algorithm -- see http://en.wikipedia.org/wiki/AES%5F%28cipher%29 | |
PeterWood: 16-Apr-2012 | The final paragraph of the section titled the algorithm in the wikipedia enttyr for Blowfish explains that it is possible to implekment the algorithm with keys of up to 576 bits long but not advised by the author of the algorithm. Though when I was using REBOL for some testing, I set the strength to 448. I would have thought that AES 256 would suffice for for most purposes needing symmetrical encryption | |
caelum: 16-Apr-2012 | AES 256 is more than sufficient for most purposes. I am researching what Rebol can do so I am aware of the parameters I am working within. I am writing code that will be used to encrypt communication between clients who want a secure communication facility. I am looking at the Rebol RSA algorithms now. Thanks for your input. | |
caelum: 2-Aug-2013 | When R3 was open sourced, I presume the SDK was not also open sourced? I am looking for the 'C' source code for the RSA, AES and Blowfish encryption functions. | |

Gabriele: 7-Jan-2005 | hmm, knowing Maarten, I guess he's actually using AES, which is 128 bit; the RSA key is probably 1024. | |
Graham: 28-Jun-2008 | All this to download the pka aes upgrade :( | |

Allen: 2-Nov-2006 | Encloak -- http://www.rebol.net/cookbook/recipes/0023.html-- Carl says Newer versions of REBOL include "cloaking" functions for encrypting and decrypting strings. These functions do not provide full strength encryption such as Blowfish, AES, or RSA as found in REBOL/Command, nevertheless they can be useful for hiding passwords and other values. (That's why we call it cloaking rather than encrypting.) | |

Rondon: 13-Jan-2012 | I'd like to encrypt json text using Rebol and AES encryption. And decrypt this using javascript. Do you have any idea how to do this using Rebol. I mean the AES encryption. I mean : txt: "blablablba" key: #CEDEFF.. encrypt txt key ... using AES rhinjael algorithm .. thanks | |
GrahamC: 13-Jan-2012 | I tried to do AES encryption but anything I encypted was not de-crpytable by standard tools | |
Gabriele: 16-Jan-2012 | Graham: IIRC Maarten was able to use AES with REBOL and OpenSSL. I seem to remember that I had tried that and was successful as well. In any case, the only reason I can think of that would make it not work is a difference in the IV and padding. | |
Cyphre: 16-Jan-2012 | Graham: I was able to implement TLS1.0 protocol configured to use the TLS_RSA_WITH_RC4_128_SHA cipher-suite. All the mentioned algorithms were calculated using the build-in Rebol2 encryption functionality. I had no problems regarding the compatibility. I haven't tried the cipher-suite with the AES enctryption though but my guess it will work as well. | |

Robert: 24-Apr-2006 | WRT encryption. I found one implementation (you need to buy a license) that supports transparent encryption. IIRC I posted the link some time ago. I will have a look at the C code and there at the storage stuff to see how hard it is to add an AES encryption of storage pages. IMO it can't be that hard. | |

GrahamC: 19-Nov-2010 | ie. I want to be sure that if I send a file encrypted using AES, that someone can decrypt it. | |
PeterWood: 19-Nov-2010 | Try here: http://www.movable-type.co.uk/scripts/aes.html | |
PeterWood: 1-Apr-2011 | RSA is not really designed to encrypt large chunks of data. You'd be better of using AES (or Rijndael as it used to be known as is still called in REBOL). RSA is better used for exchanging passwords and "signing" documents. | |
GrahamC: 1-Apr-2011 | so I would use AES to encrypt the data,and then use RSA to encrypt the AES encryption key I guess | |
GrahamC: 1-Apr-2011 | trouble is I've not had any luck with decrypting stuff encrypted by Rebol with AES by other AES decryption tools | |
PeterWood: 1-Apr-2011 | Yes you would use AES to encrypt the data and then RSA to encrypt and send somebody the encryption key. | |
PeterWood: 1-Apr-2011 | Also, from Wikipedia - AES has a fixed block size of 128 bits whereaas Rjindael can have a blocksize in any multiple of 32 between 128 and 256 bits. |
