Reversing-secrets Of Reverse Engineering -
Beyond software, reverse engineering is vital for . By reversing a strain of ransomware, security researchers can find a "kill switch" or develop a decryption tool, saving millions of dollars. In hardware, it allows for the repair of obsolete machinery where the original manufacturer no longer exists.
Reverse engineering is often misunderstood as a tool for digital piracy or industrial espionage. In reality, it is a sophisticated discipline of "backwards problem-solving"—the process of deconstructing a finished product to understand its inner logic, design, and vulnerabilities. To master the secrets of reversing is to transition from a consumer of technology to an architect of its deepest mechanics.

However, the field exists in a delicate legal balance. While the Digital Millennium Copyright Act (DMCA) and similar laws provide some protections for interoperability and research, "cracking" proprietary software for profit remains illegal. The true secret of a professional reverser is maintaining a strict ethical code: using their skills to defend systems and foster innovation rather than for exploitation. Conclusion Beyond software, reverse engineering is vital for
Examining the code without executing it. Using tools like disassemblers (e.g., IDA Pro or Ghidra), engineers map out the program’s structure. The secret here is patience—navigating thousands of lines of code to find the "main" logic. Reverse engineering is often misunderstood as a tool

делаю по документации, пароль ввожу верный для моего закрытого ключа.
Но в ответ на команду после ввода команды
crypto pki import CA_INTANDSERV pem terminal password INSERT-PRIVATE-KEY-PASSWORD
и указания своих ключей:
——END CERTIFICATE——
quit
Unable to add certificate.
% PEM files import failed.
делал на двух Cisco: 2811 с IOS
System image file is «flash:/c2800nm-adventerprisek9-mz.151-4.M10.bin»
и на cisco 7301
делаю так:
crypto pki trustpoint COMODO
enrollment terminal PEM
crl optional
exit
crypto pki authenticate COMODO
тут ввожу root сертификат COMODO
addtrustexternalcaroot.crt
потом ввожу
crypto pki authenticate COMODO
crypto pki trustpoint domain.su
enrollment terminal PEM
crl optional
exit
crypto pki import domain.su PEM terminal «password»
% Enter PEM-formatted CA certificate.
% End with a blank line or «quit» on a line by itself.
сначала ввожу данные из
comodorsaaddtrustca.crt
потом свой закрытый ключ сгенерированный на Linux машине с -des3 c тем же паролем что я указал выше, потом указываю свой crt ключь
Не указано, на каком устройстве выполняются действия. Это ASA ??? Интересно, а из коммутаторов Cisco где-то поддерживается подключение по SSH именно по сертификатам???
