夜來有一夢，解之尋 夢書，得一詩︰

《夏日登鹤岩偶成》‧ 戴叔倫

天風吹我上層岡，
露洒長松六月凉。
愿借老僧双白鶴，
碧云深處共翱翔。

， 禹步判詞曰︰天借，長。

幽思起無明，意緒難抹滅。信手翻《  》圖冊，正遇仲夏夜之夢

 

， 跳舞的仙子。想必是『花魂』『鳥魂』已歸天界了吧！

☆ 編者言

無緣讀  夢書，沒法解  禹步，因此緣法故，只作『寓釋』講， M♪o 的心情或可體會，難以言傳。

─── 《M♪O 之學習筆記本《寅》井井︰【䷝】試釋是事》

 

幾年前，譯寫 M♪O 偶遇之『駭黑事件』，當時心卻沈重那年寶島的『網路霸凌』遺憾︰

《語‧飛語‧飛飛語；言‧流言‧流流言》

如果《飛劍》可『殺人』，《飛語》令人『心碎』；

假使《流水》能『無情』，《流言》使人『絕命』。

從《茱莉亞羅伯茨妹妹自殺原因：不堪語言暴力》這篇報導，以及《茱莉亞‧羅伯茨：妹妹自殺後苦痛難熬》那篇報導，看

《流言飛語》之『語言暴力』的『悲劇』何時休？！

 

今日恰逢提筆談『劊客』 cracker 『技倆』之際︰

當下沒心緒， W!o+ 傳話至，吱吱又咭咭。聲聲皆分明，半句難了意。細思，原來是《  》笑典裡的

《施氏食獅史》‧趙元任

石室詩士施氏，嗜獅，誓食十獅。施氏時時適市視獅。十
時，適十獅適市。是時，適施氏適市。氏視是十獅，恃矢
勢，使是十獅逝世。氏拾是十獅屍， 適石室。石室濕，氏
使侍拭石室。石室拭，氏始試食是十獅。食時，始識是十
獅，實十石獅屍 。試釋是事。

☆ 編者言

編者不知『笑典』是何典？只讀著一堆音近字，方才勉強擬以相仿的《施氏食獅史》。其實『  W!o 』以及『 M♪o 』有著特殊關聯，讀者若是不知道此事，恐將以為編者穿鑿附會，特此一併表明。

！☿☹ ，W!o 平日寡言少語，這『咭吱』文，恐有『寓意』，卻是恰在此時？☿☹☺ 該不會是『魔電』 Modem 聲吧？？這倒是點醒了我一件事。

生︰《  》網上偶讀 蠻力法

Brute-force attack

In cryptography, a brute-force attack, or exhaustive key search, is a cryptanalytic attack that can, in theory, be used against any encrypted data^[1] (except for data encrypted in an information-theoretically secure manner). Such an attack might be used when it is not possible to take advantage of other weaknesses in an encryption system (if any exist) that would make the task easier. It consists of systematically checking all possible keys or passwords until the correct one is found. In the worst case, this would involve traversing the entire search space.

When password guessing, this method is very fast when used to check all short passwords, but for longer passwords other methods such as the dictionary attack are used because of the time a brute-force search takes.

When key guessing, the key length used in the cipher determines the practical feasibility of performing a brute-force attack, with longer keys exponentially more difficult to crack than shorter ones. A cipher with a key length of N bits can be broken in a worst-case time proportional to 2^N and an average time of half that.

Brute-force attacks can be made less effective by obfuscating the data to be encoded, something that makes it more difficult for an attacker to recognize when he/she has cracked the code. One of the measures of the strength of an encryption system is how long it would theoretically take an attacker to mount a successful brute-force attack against it.

Brute-force attacks are an application of brute-force search, the general problem-solving technique of enumerating all candidates and checking each one.

The term “brute-force” is not the only term to name such a type of attack. It can also be called “bruteforce”, “brute force” and just “brute” (that is common in names of programs that perform brute-force attacks).

碼︰無 習。無課。

☿ 行︰雖說是蠻力法，實則乃用『窮舉』，數ㄕㄨˇ數ㄕㄨˋ數不盡，耗時難為功，怎曉 機心迅捷後，此法遂真可行耶！？實習所用機，登入採『學號』與『針碼』【※ Pin Code 四位數字碼】 。『學號』之制 ── 班碼-位碼 ──，班不過十，位少於百，故而極其數不足千。針碼有四位，總其量，只有萬。試而盡之，『千萬』已『窮舉』。問題當在『咸澤碼訊』有多快？『登錄』之法有多嚴 ？破解程式幾人會？設使一應具足，那個『駭黑』之事，怕是恐難免！！

理雖通，程式而今初學，實作難？！☿☹。苦思腸，難不成不能『仍舊』用著『試誤法』，一探究竟！？ ☿☺ 。

經過了一番折騰，總算完成了 M♪oautologin.py ，雖看來事情並不容易 ，但是…再熟悉一點之後…… ☿☺ ，恐非難事。

 

誰知又遭台鐵『普悠瑪』慘痛事故★

能以為不巧『月行黑道』乎？

陰陽之不測，人事務求其免也☻

派︰聽聞學長說，實習機器故障，所以停課。也常常上課不實習。故不故障、上不上課、實不實習，豈關聯！事出必有因，費疑猜！！
