HTTPS proxy IP refers to the overseas real network address IP with the communication protocol of HTTPS, which is usually used in various cross-border businesses.
1. What is HTTPS protocol
HTTP is an application layer protocol that usually runs on top of TCP. It is a plain text protocol where the client initiates a request and the server responds. Since the network is not trustworthy, the plain text nature of HTTP has the following risks:
1. Communication data is at risk of being eavesdropped and tampered with
2. The target website is at risk of being impersonated
The HTTPS protocol was developed to solve this problem. It introduced the concepts of CA and digital certificates, thereby solving the problem of secure key exchange.
Digital certificate: contains information such as issuing authority, validity period, applicant's public key, certificate owner, certificate signature algorithm, certificate fingerprint and fingerprint algorithm.
CA: Digital certificate issuing authority. The authoritative CA is trusted by the operating system and will be built-in when the operating system is installed.
2. How does the HTTPS protocol ensure information security?
1. The browser requests the server's port 443 using the HTTPS protocol
2. The server sends its own digital certificate to the browser (plain text)
3. The browser first verifies whether the CA, validity period, and domain name are valid. If not, the connection is terminated (the server cannot be trusted at this time).
4. If it is valid, take out the public key of the certificate authority from the operating system, decrypt the digital signature according to the signature algorithm to obtain the certificate fingerprint and fingerprint algorithm
5. The browser uses the fingerprint algorithm obtained by decryption to calculate the fingerprint of the certificate and compares it with the fingerprint obtained by decryption. If they are consistent, the certificate is valid and the public key is also safely obtained.
6. The browser has now communicated with the real server, and the middleman cannot know the content of the communication because he does not have the website's private key
3. How to choose an overseas https proxy ip?
1. Choose a dual-protocol proxy that integrates both https and socks5. It is more compatible with more of our own applications and can be used in different scenarios. It can also ensure our information security.
2. Choose a more stable and fast proxy. A stable proxy can ensure the smooth operation of the business. If the connection is often disconnected or the data cannot be uploaded/uploaded, it will seriously affect our data security and the smooth operation of the business. You can use the speed test website to test the speed after purchasing the proxy: fast.com
3. More proxy pools. The more proxy IPs in the supplier's proxy pool, the stronger the supplier is, and the quality of services and agents is more guaranteed. All Kookeey proxies fully support https, are pure, safe and stable, have dynamic and static devices, and are suitable for cross-border business.
