Survey: time spent per week. Is Encryption Safe?. Yes, Encryption is safe. The amount of time, energy and cost to crack most modern cryptographic technologies makes the act of attempting to decrypt encrypted code an expensive task that is, virtually speaking, inevitable. Although encryption does have vulnerabilities that rest largely outside of the power of the technology. Meaning if you give someone a USB with the key or tell them it.. Cryptography. Is:.
