CSR
Certificate Signing Request.
Message sent from applicant to registration authority of the public key infrastructure to apply for a digital identity certificate. Includes a public key. CA embeds the public key in the certificate.
EAP Authentication Protocol
Extensible Authentication Protocol.
Two systems create a secure encryption key, known as a pairwise master key (PMK). Systems then use this key to encrypt all data transmitted between the devices
Key Stretching
Increase the strength of stored passwords with a salt. Also called key strengthening. Bcrypt and PBKDF2 are key stretching techniques.
