Cryptography safeguards your organization’s data and information from potential threats and ensures that even if an intruder gained access to your company’s sensitive information, it’s very unlikely they’ll be able to read any of it.
Cryptography also helps organizations meet industry regulations. If your organization handles data that might include customer financials and account information, cardholder data and transactions and non-public personal information, it’s highly likely that data generated and/or used by your organization has strict regulations and compliance guidelines.
Symmetric cryptography is widely used to keep data confidential. It can be very useful for keeping a local hard drive private, for instance; since the same user is generally encrypting and decrypting the protected data, sharing the secret key is not an issue.
Symmetric cryptography can also be used to keep messages transmitted across the internet confidential; however, to successfully make this happen, you need to deploy our next form of cryptography in tandem with it.
Another major type of cryptography, asymmetric cryptography, is a process that uses a pair of related keys — one public key and one private key — to encrypt and decrypt a message and protect it from unauthorized access or use.
A public key is a cryptographic key that can be used by any person to encrypt a message so that it can only be decrypted by the intended recipient with their private key. A private key — also known as a secret key — is shared only with key’s initiator.
When someone wants to send an encrypted message, they can pull the intended recipient’s public key from a public directory and use it to encrypt the message before sending it. The recipient of the message can then decrypt the message using their related private key.
