SSL Complete Guide 2021: HTTP to HTTPS - Using OpenSSL for RSA Keys Generation

This video tutorial provides a comprehensive guide on using OpenSSL for generating and managing RSA keys. It covers the process of generating RSA keys, encrypting private keys with different algorithms, storing them securely in PEM files, and extracting public keys from private keys. Additionally, it demonstrates generating keys of various lengths and discusses the importance of key security.

What is the primary risk of displaying a private key directly in the terminal?

• It automatically deletes after a few minutes.

• It slows down the computer.

• It takes up too much space on the screen.

• It can be easily copied by anyone watching.

Which algorithm is mentioned for encrypting private keys in OpenSSL?

• MD5

• RSA-2048

• AES-256

• SHA-256

What file extension is commonly used for storing encrypted private keys?

• .enc

• .txt

• .pem

• .key

How can you extract a public key from a private key using OpenSSL?

• By using a text editor to copy the key.

• By using the 'openssl genrsa' command.

• By using the 'openssl rsa' command with specific options.

• By directly editing the private key file.

What is the relationship between public and private keys?

• The private key is derived from the public key.

• They are unrelated and used for different purposes.

• The public key is derived from the private key.

• They are identical and interchangeable.

What is the default length of an RSA key generated by OpenSSL?

• 1024 bits

• 2048 bits

• 8192 bits

• 4096 bits

Why might generating a longer RSA key take more time?

• It involves more user input.

• It requires more computational power.

• It uses a different algorithm.

• It needs more memory.
