Package pbkdf2 implements the key derivation function PBKDF2 as defined in RFC
2898 / PKCS #5 v2.0.
A key derivation function is useful when encrypting data based on a password
or any other not-fully-random data. It uses a pseudorandom function to derive
a secure encryption key based on the password.
While v2.0 of the standard defines only one pseudorandom function to use,
HMAC-SHA1, the drafted v2.1 specification allows use of all five FIPS Approved
Hash Functions SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512 for HMAC. To
choose, you can pass the `New` functions from the different SHA packages to
pbkdf2.Key.
*/

import (

// Key derives a key from the password, salt and iteration count, returning a
// []byte of length keylen that can be used as cryptographic key. The key is
// derived based on the method described as PBKDF2 with the HMAC variant using
// the supplied hash function.
//
// For example, to use a HMAC-SHA-1 based PBKDF2 key derivation function, you
// can get a derived key for e.g. AES-256 (which needs a 32-byte key) by
// doing:
//
// dk := pbkdf2.Key([]byte("some password"), salt, 4096, 32, sha1.New)
//
// Remember to get a good random salt. At least 8 bytes is recommended by the
// RFC.
//
// Using a higher iteration count will increase the cost of an exhaustive
// search but will also make derivation proportionally slower.

# NOTE
This implementation is direct fork of Kylom's implementation. I claim no authorship over this code apart from some minor modifications.
Please be aware this code **has not yet been reviewed**.
ecies implements the Elliptic Curve Integrated Encryption Scheme.
The package is designed to be compliant with the appropriate NIST
standards, and therefore doesn't support the full SEC 1 algorithm set.
STATUS:
ecies should be ready for use. The ASN.1 support is only complete so
far as to supported the listed algorithms before.
CAVEATS
1. CMAC support is currently not present.
SUPPORTED ALGORITHMS
SYMMETRIC CIPHERS HASH FUNCTIONS
AES128 SHA-1
AES192 SHA-224
AES256 SHA-256
SHA-384
ELLIPTIC CURVE SHA-512
P256
P384 KEY DERIVATION FUNCTION
P521 NIST SP 800-65a Concatenation KDF
Curve P224 isn't supported because it does not provide a minimum security
level of AES128 with HMAC-SHA1. According to NIST SP 800-57, the security
level of P224 is 112 bits of security. Symmetric ciphers use CTR-mode;
message tags are computed using HMAC-<HASH> function.
CURVE SELECTION
According to NIST SP 800-57, the following curves should be selected:
+----------------+-------+
| SYMMETRIC SIZE | CURVE |
+----------------+-------+
| 128-bit | P256 |
+----------------+-------+
| 192-bit | P384 |

TODO
1. Look at serialising the parameters with the SEC 1 ASN.1 module.
2. Validate ASN.1 formats with SEC 1.
TEST VECTORS
The only test vectors I've found so far date from 1993, predating AES
and including only 163-bit curves. Therefore, there are no published
test vectors to compare to.
