Remove cryptographic keys from RAM
Summary
Cryptographic keys should not remain in RAM for more than 5 seconds.
Description
When cryptographic keys are used for encryption or decryption operations, they are loaded into the computer's or device's RAM. Even after the cryptographic operation is completed, there is a risk of residual data remaining in the RAM. This residual data might persist for a short period before being overwritten by other data.
