Simply put, symmetric encryption uses the same key to encrypt and decrypt. Meanwhile, asymmetric encryption on the other hand uses different sets of keys for encrypting and decrypting.

For data/ information stored on physical storage media like paper and diskettes, mechanical devices such as pulverizers and shredders can be used to permanently wipe off data.
