Secure Socket Layer (5)
- Message transfer is 40 bit RC4 (export) and 128 bit RC4 (in USA)
- Public key cryptography - RSA 1024 bit, D-H
- HTTP protocol is using port 80 (by default); HTTP+SSL (https://…) is using port 443 by default
- Naming convention for SSL enabled servers: HTTPS, FTPS, NNTPS
- The same server can run both secure and insecure servers simultaneously: access to catalog of products can be insecure, whereas ordering and payment should be done through the secure channel
- Non-SSL browser cannot access https server
