| 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. | ||||

 | ||||
| // 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

 | ||||
| // RFC.

| 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. | ||||

 | ||||
| ecies should be ready for use. The ASN.1 support is only complete so | ||||

| 
 | ||||
| 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 | | ||||
|     +----------------+-------+ | ||||
|     |     256-bit    |  P521 | | ||||
|     +----------------+-------+ | ||||
| 
 | ||||
| 
 | ||||
| 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. | ||||
