Sandisk secure access private and public

Private keys are generated using the same algorithms that create public keys to create strong keys that are bonded mathematically.

What is a private key? Unlike the publicly accessible public key, the private key is a secret key known only by its owner, with the private key and public key paired such that the recipient can use the corresponding key to decrypt the cipher text and read the original message. Standards organizations like the CA/Browser Forum define baseline requirements for supported key sizes. This key length offers sufficient cryptographic security to keep hackers from cracking the algorithm. For example, 2048-bit RSA keys are often employed in SSL certificates, digital signatures, and other digital certificates. The key size or bit length of public keys determines the strength of protection. These algorithms use various computation methods to generate random numeric combinations of varying length so that they cannot be exploited with a brute force attack. The most common algorithms used to generate public keys are: Public keys are created using a complex asymmetric algorithm to pair them with an associated private key. What is a public key? The public key is published for all the world to see. Note that this encryption and decryption happens automatically and is invisible to the user. In short, the main difference between a public key vs private key is that one encrypts while the other decrypts. Then the other key is used as a decryption key to decrypt this cipher text so that the recipient can read the original message. In public key cryptography, an encryption key (which could be the public or private key) is used to encrypt a plain text message and convert it into an encoded format known as cipher text. The Difference Between Public Keys and Private Keys What enables this is that public keys can be distributed widely and openly without malicious actors being able to discover the private key required to decrypt the message. The public key cryptography architecture is so scalable that it is able to secure billions of messages exchanged daily by organizations over their own networks and across the internet. Additionally, symmetric key algorithms cannot easily scale as it is nearly impossible to coordinate the vast number of connections necessary to privately share all necessary combinations of private keys. Using symmetric key algorithms, with two private keys, requires that both parties in the communication have access to the secret keys, increasing the risk as both now need to keep the secret. While it may seem counterintuitive, using a key pair consisting of two private keys for encrypting and decrypting sensitive information is not more secure than asymmetric cryptography.

What makes the process secure is that the private key is kept secret by its owner, and no one is ever required to reveal or share a private key. The primary benefit of public key cryptography is increased data and identity security at scale. The key pair is mathematically related so that whatever is encrypted with a public or private key can only be decrypted by its corresponding counterpart. This private key is a secret key, and must remain known only to the recipient. The public key is comprised of a string of random numbers and can be used to encrypt a message, which only the intended recipient can decipher and read by using the associated private key, which is also made of a long string of random numbers. Public key cryptography uses cryptographic algorithms to protect identities and data from unauthorized access or use, guarding against attacks from cybercriminals and other malicious actors. Pairing two cryptographic keys in this manner is also known as asymmetric cryptography. These two keys are used together to encrypt and decrypt a message. The core technology enabling PKI is public key cryptography, an encryption mechanism that relies upon the use of two related keys, a public key and a private key.
