S2X Crypto

NIS-certified cryptographic module requiring KCMVP validation

S2X Crypto

The Korean Cryptographic Module Validation Program (KCMVP) is a program introduced to securely protect important business data communicated or stored by the government, public institutions, and enterprises.


SAESOL Tech’s cryptographic module, S2X Crypto, successfully completed validation at Security Level 1 through KCMVP, proving it is safe and reliable.

It also enables easy application of KCMVP by providing OpenSSL API compatibility.
