How to encrypt a stream?

Hi folks,

I need to encrypt a stream.

I want to write a file like:
StandardFileStream fileNamed: 'encryptedfile' do: [:str | str nextPutAll: 'string to be encrypted'].

of course the file is in plain text :-)

It would be wonderful if I can write something like:
EncrypedFileStream fileNamed: 'encryptedfile' do: [:str | str nextPutAll: 'string to be encrypted'] using: 'AES' andPassword: '12345'

Can you help me, please?

Cheers
Frank

Hi,

Have you seen the Cryptography package, you can get it by downloading Nacl from Configuration Browser. It implements RC4 which is a Stream Cipher, but seems that a little bit of work is needed in order to use it on a Stream since it receives a ByteArray.

Cheers,
Alejandro

Re: How to encrypt a stream?

My bad, the configuration is called ApplicationSecurity, which includes Nacl and Cryptography.
