Asymmetric Encryption requires two keys: a Public key and a Private key. These keys can be used to perform Encryption and Message Signing. Encryption provides Confidentiality, and Message Signatures provides Integrity and Authentication.
This lesson is a free sample lesson from the the greatest TLS and SSL training course ever created. No instructor rambling on about pointless stories. No slides with massive walls of text. No time wasting. Only simple, effective, and precise explanations. Complimented with practical illustrations and visuals.
🔐 More details about the course:

🏢 Do you configure or troubleshoot TLS/SSL for work? If so, I'm willing to bet your employer would happily pay for this SSL training. Reach out if you'd like to coordinate an introduction for a bulk license purchase with your company. I'm happy to provide a generous referral bonus =)

I’m watching these types of videos for better understanding of specific types of concepts covered in Security+. Also I’ve been personally using technology since the days of original Oregon Trail as a hobby. As my first ever KZhead comment: These videos are fantastic videos. You deserve way more subscribers than you have. Fantastic explanations man. Bravo.

  • Thanks for the great video. I found the factors P and Q for the number 1909: P=23, Q=83. To do this, I used the "Quadratisches Sieb" factorization procedure, which operates as follows: First I calculate the square root of 1909 which gives the value "43.69". After that I set the factors P = 43 and Q = 44. Now the calculations follow. If I calculate P*Q (43*44), then this results in "1892". Since this value is smaller than "1909" I increase Q by one -> Q=45. Now I calculate again the product P*Q (43*45) -> "1935". The value is now greater than "1909", so I decrease P by the value 1 -> P=42. I follow these rules until the value 1909 is calculated. Summary: - P*Q (43*44) -> 1892 < 1909 -> Q+1 (45) - P*Q (43*45) -> 1935 > 1909 -> P-1 (42) - P*Q (42*45) -> 1890 < 1909 -> Q+1 (46) - P*Q (42*46) -> 1932 > 1909 -> P-1 (41) ..... - P*Q (23*83) -> 1909 = 1909 I hope this is helpful.

    • Great write up! This proves 2 things: 1. Any key can be solved via brute force 2. Brute force doesn't necessarily require trying _every_ possibility, there are shortcuts you can take as you did =) Going to pin your post, to bring more attention to your write up and hopefully your channel. Good stuff!
