# What is Key Check Value for a Fortanix DSM security object ?

The [Key Checksum Value (KCV)](https://en.wikipedia.org/wiki/Key_checksum_value) is the checksum of a cryptographic key. It is used to validate the key integrity or match the keys without knowing their actual values.

Fortanix-Data-Security-Manager (DSM) automatically calculates the KCV for any key generated or imported into the system. The KCV is derived using standard cryptographic practices and represents a 24-bit value computed from the key material. This value serves as a short fingerprint of the key and is commonly used to verify the integrity of the key.

Fortanix Data Security Manager (DSM) is the world’s first cloud service secured with Intel® SGX. With Fortanix DSM, you can securely generate, store, and use cryptographic keys and certificates, as well as other secrets such as passwords, API keys, tokens, or any blob of data. Your business-critical applications and containers can integrate with Fortanix DSM using legacy cryptographic interfaces (PKCS#11, CNG, and JCE) or using the native Fortanix DSM RESTful interface.
