Detailed Description

MD2 Message-Digest algorithm.

The algorithm takes as input a message of arbitrary length and produces as output a 128-bit message digest of the input. It is conjectured that it is computationally infeasible to produce two messages having the same message digest, or to produce any message having a given prespecified target message digest.

uint8_t* md2_end

(

Md2Context *

context

)

Ends an MD2 message digest operation.

This fuction take an context and return a pointer to context state.

Parameters:

context

in input.

Returns:

a pointer to context state (message digest).

bool md2_test

(

void

)

MD2 test fuction.

This function test MD2 algorithm with a standard string specified in RFC 1319.

Note:

This test work with official array of 256 byte pemutation contructed from digits of pi, defined in the RFC 1319.
