I think this picture is wrong :

In the article http://en.wikipedia.org/wiki/Public-key_cryptography i read that "The public key is used to transform a message into an unreadable form, decryptable only by using the (different but matching) private key." and I think this is right, so, I don't think that one can decipher anything using a public key as shown on the picture.

It's correct. --Piercosta (talk) 16:14, 19 March 2014 (UTC)[reply]

For clarification if you're still confused, or for anyone else who stumbles on this, the image is indeed correct. The context of your quote was about public-key encryption, which aims to protect the contents of a file or message. Digital signatures aim to provide authentication and non-repudiation. They are mathematically similar, but different in purpose. 74.69.40.245 (talk) 21:59, 31 May 2014 (UTC)[reply]
