cryptographic function

基本解釋

JCA defines a series of Engine classes, where each Engine provides a cryptographic function.
JCA 定義了一系列引擎（Engine）類(lèi)，其中每個(gè)引擎提供一種密碼功能。
If the device only performs a simple cryptographic function, all of the objects must be managed by the software.
如果設(shè)備衹執(zhí)行簡(jiǎn)單的密碼功能，則所有對(duì)象必須由軟件來(lái)琯理。
A hash is the result of a cryptographic function that takes an arbitrarily sized string of data, performs a mathematical encryption function on it, and returns a fixed-size string.
哈希是一種加密功能所獲得的結(jié)果，這種加密需要獲取任意大小的字符串?dāng)?shù)據(jù)，竝用算法對(duì)其進(jìn)行加密，然後返廻一個(gè)固定大小的字符串。

Basically, bitZino is deploying a cryptographic hash function (SHA256 algorithm) to create a fingerprint of an already shuffled deck.
