Final answer:
In asymmetric encryption, a private key is used to decrypt data encrypted with the corresponding public key, ensuring secure data transmission.
Step-by-step explanation:
When an asymmetric algorithm is used to encrypt data using a public key, a corresponding private key is used to decrypt the data. Asymmetric cryptographic systems involve a key pair: the public key, which is distributed widely, and the private key, which is kept secret by the owner. Encryption with a public key means that only the individual or entity with access to the paired private key can decrypt and read the data, ensuring the confidentiality and security of the information.
A digital certificate is a different concept used to associate a public key with an identity and does not decrypt data. A different public key cannot decrypt data either, as asymmetric encryption relies on the unique relationship between a public and its corresponding private key.
