Public keys in asymmetric encryption are distributed over the public-key servers. So, there is no need to worry about public disclosure of keys as they can’t be used to access your information.

Asymmetric encryption (public-key algorithms) involves a key pair: a public key for encryption or signature verification and a private key for decryption or signing.

In the context of cryptography, a public key is an alphanumeric string that serves as an essential component of asymmetric encryption algorithms. It is typically derived from a private key, which must ...

The first public key encryption algorithm: RSA The first algorithms using asymmetric keys were devised in secret by the British government's SIGINT agency, GCHQ, in 1973.

The algorithm they presented in 1976, known as Diffie-Hellman, introduced the general notion of what is now called asymmetric encryption, or public-key cryptography.
