Inflight network data encryption

A method comprising:

• receiving, by a first network adapter card, a first data from a server via a network file system (NFS) protocol, wherein the first data is to be transmitted to a network attached stored (NAS) device via a first network adapter card, wherein the first network adapter card is configured for inflight encryption of the first data;
• determine that the first data from a server was received via an NFS port of a plurality of ports;
• determining, by the first network adapter card, that the first data is unencrypted based at least in part on receiving the first data via an NFS port of the plurality of ports;
• encrypting, by the first network adapter card, the first data based at least on part on the first data being received via the NFS port;
• and
• transmitting the encrypted first data to NAS device via the second network adapter card, wherein the second network adapter card is configured for inflight decryption of the encrypted first data received from the first network adapter card.

A non-transitory computer-readable medium comprising program code that is executable by a processor for causing the processor to:

• receive, by a first network adapter card, a first data from a server via a network file system (NFS) protocol, wherein the first data is to be transmitted to a network attached stored (NAS) device via a first network adapter card, wherein the first network adapter card is configured for inflight encryption of the first data;
• determine that the first data from a server was received via an NFS port of a plurality of ports;
• determine, by the first network adapter card, that the first data is unencrypted based at least in part on receiving the first data via an NFS port of the plurality of ports;
• encrypt, by the first network adapter card, the first data based at least on part on the first data being received via the NFS port;
• and
• transmit the encrypted first data to the NAS device via the second network adapter card, wherein the second network adapter card is configured for inflight decryption of the encrypted first data received from the first network adapter card.
