I'm working in Base64 in Ruby on Rails and have a question:
For example how would the following be Base64 encoded / decoded?
<a href="myroute?id=<%[email protected]%>"> MY LINK</a>

To create Base64 try this:
def create_base_64
begin
#for create
a = 1
b = Base64.encode64(a.to_s)
# for decoding
c = Base64.decode64(b)
puts c
rescue Exception => e
puts e
end
end
For more security try to broke it. For example:
b[1] = b[1] << SecureRandom.hex(1)
And other action, you recived the param b:
b = params[:b]
b[2]=""
b[2]=""
c = base64.decode64(b.to_s)

thanks, i work with example... but your broke the base64 and reassembled again the base64

do not rely on security through obscurity
ActiveSupport::Base64.encode64(`whateveryouwanttoencode`)
You don't really provide enough detail about what exactly you want to do. . . The method I provided is how you accomplish Base64 encoding though, is that all you need?
Some documentation: http://www.rubydoc.info/docs/rails/3.0.0/ActiveSupport/Base64

@pedroooo No problem, his post wasn't here when I was writing this. Just trying to get you going in the right direction.

For me works just
Base64.encode64, without ActiveSupport.I don't understand what you are trying the achieve with your anchor tag example. But to decode a base64 in ruby you would do this:
base64_string = "67382hfuisab3y289321787123890......"
decoded_data = StringIO.new(Base64.decode64(base64_string))
and then do whatever you want with decoded_data
