Keys

The thing that decrypts the encrypted things is called a keys.So that encryption can have many types of keys in it, it is so that not everyone can break it.There is also a way but they have private keys.

symmetric cryptography
Encryption and Decryption are both same keys that is called symmetric Cryptography.
A symmetric cryptography
Encryption and decryption are different keys that is called A symmetric cryptography.

How does it make cryptocurrencies secure

we can secure cryptocurrency by encryption and decryption.We can very well protect cryptocurrencies.Bit college is digital currency and check currency is decentralized.No one can take care and hold this curriences from the government.and it itself is very regulated.And it goes from one wallet to another in the case of digital currency.This transaction works as a protection for so that when you do the transaction, your money cannot be stolen.Every digital currency uses encryption to make your transactions secure.
