Again, you do not understand how data encryption works, if you claim that they have back doors. 

Leo is partially right. NSA has introduced backdoors into encryption algorithms that itself help create. 

In 2013, interest began to increase considerably when it was discovered that the NSA had potentially implemented a backdoor into the P-256 curve based Dual_EC_DRBG algorithm.[11] While not directly related,[12] suspicious aspects of the NIST's P curve constants[13] led to concerns[14] that the NSA had chosen values that gave them an advantage in breaking the encryption.[15][16]

However, there are elliptic curves that are currently mathematically unbreakable. You just have to use the right one.

Choosing constants for encryption algorithms is not "installing back doors".
Choose the constants that are considered standard practice by the industry, or use an open source library that does that for you because it is notoriously difficult.

Also, do not take security advice from Leo, his website stores user passwords as plain unencrypted, unhashed text.
