    Sniffing traffic with TLS v1.3

    • kajal
    The wolfSSL library includes a useful tool for sniffing TLS traffic. This can be used to capture and decrypt live or recorded PCAP traces when at least one of the keys is known. Typically a static RSA ciphersuite would be used, however with TLS v1.3 only Perfect Forward Secrecy (PFS)...

    What is a Block Cipher?

    • rylie
    A block cipher is an encryption method that applies a deterministic algorithm along with a symmetric key to encrypt a block of text, rather than encrypting one bit at a time as in stream ciphers. For example, a common block cipher, AES (Advanced Encryption Standard), encrypts 128 bit blocks with...

    What is a Stream Cipher?

    • rylie
    A stream cipher encrypts plaintext messages by applying an encryption algorithm with a pseudorandom cipher digit stream (keystream). Each bit of the message is encrypted one by one with the corresponding keystream digit. Stream ciphers are typically used in cases where speed and simplicity are both requirements. If a 128...
