Cryptography in web development?

I study on a specialty "cyber security", exploring all sorts of items including, specialty where he held a number theory now reached elliptic curves. On programming learn C/C++. Although I myself am learning PHP/JS, layout and overall look of the web, want to develop in this direction, make your website. The question is: do I need developer knowledge of cryptography, all algorithms Snorre, etc.?

For "normal" websites don't need to. Mostly used what is in the browsers.
Unusual is sometimes used - the same miners js, or strong encryption on the client in some instant messengers or file sharing sites like mega.
But such tasks are rare.
