## Captcha Bypass

Ili **kuepuka** captcha wakati wa **mtihani wa seva** na kujiendesha kwa kazi za kuingiza mtumiaji, mbinu mbalimbali zinaweza kutumika. Lengo si kudhoofisha usalama bali kuboresha mchakato wa mtihani. Hapa kuna orodha kamili ya mikakati:

1. **Kuharibu Parameta**:
* **Acha Parameta ya Captcha**: Epuka kutuma parameta ya captcha. Jaribu kubadilisha njia ya HTTP kutoka POST hadi GET au vitenzi vingine, na kubadilisha muundo wa data, kama kubadilisha kati ya data ya fomu na JSON.
* **Tuma Captcha Tupu**: Wasilisha ombi lenye parameta ya captcha lakini ikiwa tupu.

2. **Uondoaji wa Thamani na Utumiaji Tena**:
* **Ukaguzi wa Kanuni ya Chanzo**: Tafuta thamani ya captcha ndani ya kanuni ya chanzo ya ukurasa.
* **Uchambuzi wa Kuki**: Chunguza kuki ili kuona kama thamani ya captcha imehifadhiwa na kutumika tena.
* **Tumia Thamani za Captcha za Zamani**: Jaribu kutumia thamani za captcha zilizofanikiwa hapo awali tena. Kumbuka kwamba zinaweza kuisha muda wakati wowote.
* **Kuharibu Kikao**: Jaribu kutumia thamani ile ile ya captcha katika vikao tofauti au kitambulisho cha kikao kilekile.

3. **Automatisering na Utambuzi**:
* **Mathematical Captchas**: Ikiwa captcha inahusisha operesheni za hisabati, jiendeshe katika mchakato wa hesabu.
* **Utambuzi wa Picha**:
* Kwa captchas zinazohitaji kusoma wahusika kutoka picha, tambua kwa mikono au kimaandishi jumla ya picha za kipekee. Ikiwa seti ni ndogo, unaweza kutambua kila picha kwa hash yake ya MD5.
* Tumia zana za Utambuzi wa Wahusika wa Kijamii (OCR) kama [Tesseract OCR](https://github.com/tesseract-ocr/tesseract) ili kujiendesha katika kusoma wahusika kutoka picha.

4. **Mbinu za Ziada**:
* **Kujaribu Kiwango cha Kiwango**: Angalia ikiwa programu inapunguza idadi ya majaribio au uwasilishaji katika muda fulani na ikiwa kikomo hiki kinaweza kuepukwa au kurekebishwa.
* **Huduma za Tatu**: Tumia huduma za kutatua captcha au APIs zinazotoa utambuzi wa captcha wa kiotomatiki na kutatua.
* **Mzunguko wa Kikao na IP**: Badilisha mara kwa mara vitambulisho vya kikao na anwani za IP ili kuepuka kugunduliwa na kuzuia na seva.
* **Kuharibu User-Agent na Vichwa**: Badilisha User-Agent na vichwa vingine vya ombi ili kuiga vivinjari au vifaa tofauti.
* **Uchambuzi wa Captcha ya Sauti**: Ikiwa chaguo la captcha ya sauti linapatikana, tumia huduma za sauti hadi maandiko kutafsiri na kutatua captcha.
