Subject: rescue'ing OpenSSL errors

Hi! I'm having some issues with the OpenSSL library:

I'm trying to rescue whatever errors the library wants to throw,  
however, it's not working:

def encrypt
     require 'openssl'
     begin
       aes = OpenSSL::Cipher::Cipher.new('AES-128-CBC')
       aes.encrypt('SOME_KEY')
       cipher =  aes.update(password)
       cipher << aes.final
       return cipher
     rescue
       return false
     end
end

Now I go into irb:

require 'encrypt'

encrypt('test') # -> gives encrypted output
encrypt('') # -> gives error "evp_enc.c(332): OpenSSL internal error,  
assertion failed: inl > 0 \n Abort trap"

Seems like I can't rescue that because the error comes from a C  
library. Is that right?


Are there any solutions to this, except, for example, checking that  
"not password.empty?" ?




Thanks, Rob
