+ Integrate elliptic curve contribution from Andreas
+ Schultz </p>
+ <p>
+ In order to be able to support elliptic curve cipher
+ suites in SSL/TLS, additions to handle elliptic curve
+ infrastructure has been added to public_key and crypto.</p>
+ <p>
+ This also has resulted in a rewrite of the crypto API to
+ gain consistency and remove unnecessary overhead. All OTP
+ applications using crypto has been updated to use the new
+ API.</p>
+ <p>
+ Impact: Elliptic curve cryptography (ECC) offers
+ equivalent security with smaller key sizes than other
+ public key algorithms. Smaller key sizes result in
+ savings for power, memory, bandwidth, and computational
+ cost that make ECC especially attractive for constrained
+ environments.</p>

+ Make the crypto functions interruptible by chunking input
+ when it is very large and bumping reductions in the nifs.</p>
+ <p>
+ Not yet implemented for block_encrypt|decrypt/4</p>
+ <p>
+ Impact: Individual calls to crypto functions may take
+ longer time but over all system performance should
+ improve as crypto calls will not become throughput
+ bottlenecks.</p>
