有無方法可以估到加密方法?

有堆咁既密碼, 估計可能係hashcode, 當然唔排除係symmetric, 因為已知input長度係固定的

睇樣, 感覺有D似bcrypt, 但短好多, 多數係類似既野, 假設依個係用common 既algorithm整出黎, 估唔估到係邊種加密?

似 128-bit value 用 base64 encode 咗

hash 嘅話就 "decrypt" 唔到

但係 hash 又唔會咁啱全部 "z" 開頭

以下係Base64 Decode後轉返做Hex:

複製代碼
(唔知endian啱唔啱……)
樓主係由一個Sorted List拎堆Value出黎?係既話全部CF開頭都唔出奇
32byte (128-bit)既話可能係MD5,但得Output冇Input好難估……

TOP

呢個係唔係用來recruit數學天才的post?

TOP

無意思
因為俾你解返a-z0-9出黎又如何,可能每隔幾個位遞增再對應返特定解碼表
唔一定要內容全部內嵌係呢段文字上

TOP

樓主係咪接咗個舊 system 返嚟 revamp?

152-bit 好似 WEP key .....

TOP

個input唔係100% sure, 但估佢九成應該係果個input

example 1
hIKRbnwnBt2F3P0Ul37p7Q==
input應該係0x046FCF4A773480

example 2
nslLqTTThNcx23gBTBcTVA==
input應該係0x04708C4A773480

唔打算decode, 只求知道佢點encode

排得咁好似 SN 多d

你整三四條相同 input, 睇吓 output 係咪唔同.

(可以嘅話, 整夠 512 行, 睇吓有冇 collision  )

首先你要有一set cluster computers
