Guys who plan to use blockchain.info online wallet please consider:
Hi blockchain.info support,
i wrote a mail complaining a possible security issue to you on 12. Oct and got no reply so far.
Therefore i will post the answer here and hope to get feedback soon:
"In the qr code for iphone device pairing the plaintext login password is contained. this is (in my opinion) a possible security issue and it makes me nervous because this means that my login password is stored in a way which is decryptable ( normally i would have expected that the password is stored as a salted hashvalue). so please can you explain."
Kind regards
