Java SSLSocket พร้อม TLS1.3 และ TLS_AES_128_GCM_SHA256 Cipher Example
เผยแพร่แล้ว: 2020-07-18
จะส่งคำขอ TLS1.3 HTTPs ไปยังโดเมนของคุณและพิมพ์การตอบกลับได้อย่างไร
คลาส SSLSocket ขยาย Socket
และจัดเตรียมซ็อกเก็ตที่ปลอดภัยโดยใช้โปรโตคอล เช่น โปรโตคอล “Secure Sockets Layer” (SSL) หรือ IETF “Transport Layer Security” (TLS)
ในบทช่วยสอนนี้ เราจะตั้งค่าโปรโตคอล TLS1.3
และการเข้ารหัส TLS_AES_128_GCM_SHA256
มาเริ่มกันเลย:
- สร้างไฟล์ CrunchifySSLTLS13Tutorial.java
- ตั้งค่าโปรโตคอล: TLS1.3
- ตั้งค่าการเข้ารหัส: TLS_AES_128_GCM_SHA256
- โทร HTTP 1.0 ไปที่ crunchify.com
- โทร HTTP 1.0 ไปที่ google.com
- พิมพ์ตอบกลับ

นี่คือโปรโตคอล TLS1.3 ที่กำหนดไว้:
- TLS_AES_128_CCM_8_SHA256
- TLS_AES_128_CCM_SHA256
- TLS_AES_128_GCM_SHA256
- TLS_AES_256_GCM_SHA384
- TLS_CHACHA20_POLY1305_SHA256
ผลลัพธ์:
บน Crunchify เรา TLS1.3 enabled
และด้วยเหตุนี้จึงไม่มีข้อผิดพลาดใด ๆ ที่เราได้รับ
