Private Key Is Just Number Four

4 times the SECP384-R1 base point is (0x138251cd52ac9298c1c8aad977321deb97e709bd0b4ca0aca55dc8ad51dcf9d 1589f15?7ea5120e1fed?c63e1835, 0xacae2986a2be1631e8a28181ab5616dc45d918abc09f3ab0e63cf792aa4dce d7387be37bba56954f1c02b270ed67) repository.emsign.com/certs/EM... for the non-cryptographers at the back of the room: the private key is 4, just the number 4, nothing more Certificate: Data: Version: 3 (0x2) Issuer: C=IN, O=eMudhra Technologies Limited, CN=emSign Root TLS CA - G3 Subject: C=US, O=eMudhra Inc, CN=EM OV TLS CA - G3C Subject Public Key Info: Public Key Algorithm: id-ecPublicKey Public-Key: (384 bit) pub: 04:13:82:51:cd:52:ac:92:98:c1:c8:aa:d9:77:32: 1d:eb:97:e7:09:bd:0b:4c:a0:ac:a5:5d:c8:ad:51: dc:fc:9d:15:89:a1:59:7e:3a:51:20:e1:ef:d6:31: c6:3e:18:35:ca:ca:e2:98:69:a6:2e:16:31:e8:a2:

A cryptography joke shows a post claiming that four times the SECP384-R1 base point is a long hexadecimal value, followed by a certificate dump. The punchline says that, for non-cryptographers, the private key is simply the number 4, parodying the intimidating complexity of elliptic-curve cryptography. It is shared as a nerdy reaction to overly complicated technical explanations.
