u think it is a mistake.

Looks like your composer wanted SSL3 and packagist disabled it.
Make sure you have the latest composer, and php/OpenSSL libs.

If that's not it, maybe it's really a man-in-the-middle attack.
In any case the problem is with composer, not magento.

Hi @vsikarwar, have you resolved the issue?

Hi,

Yes I have fixed the issue. That was the composer problem.

Now I have successfully resolved the issue.

Can I go live with the code.

@vinaysikarwar can you please share, how you addressed this issue?

[alexkoepke]

@hirensoni2005 I can't remember what I did exactly. But have you tried clearing your composer cache?

Should be located in ~/.composer
