Good news from Lexar – one of the world’s bigger CompactFlash manufactures – as they start shipping their security oriented Lexar LockTight CompactFlash. Lexar’s LockTight CompactFlash support encryption and the ability to establish security settings on the memory card and digital camera to prevent unauthorized use – read and write – of the CompactFlash.

The encryption algorithm is said to utilize 160 bit encryption technology, using the SHA-1 (Secure Hash Algorithm), a standard approved by the NIST (National Institute of Standards and Technology).
