Use a hash algorithm, more specifically a one-way hash function, to turn your message into a hash, a condensed version of the message. Encrypt the hash with your private key, or sign the message, so the recipient can decrypt with your public key. ...

Public-key cryptography started with the realization that it should be possible to design encryption schemes in which it is computationally infeasible to find the decryption algorithm from the encryption one. This, in turn, entails that the same key cannot be used for both encryption and decryption...
So we use digest algorithm to generate afixed-lengthbits of number from original data, which can do encryption faster. The original data is corresponded with the digest number, just like a key-value pair. MD5 is a commonly used digest algorithm. ...
This library uses a 2048 bitRSApublic key to encrypt a generated (per instance ofPPK) 128 bitAESkey which is prepended to the AES encrypted message. The RSA algorithm used isRSA/ECB/OAEPWithSHA1AndMGF1Paddingwhich usesOptimal Asymmetric Encryption Padding. This RSA variant has improved strength...
public-key encryption scheme In subject area: Computer Science A public-key encryption scheme is defined as a cryptographic system that uses a pair of keys - a public key for encryption and a private key for decryption. It is commonly used in secure communication protocols like SSL to ...
private key pair and the fact that Alice and Bob agree on a public, standard encryption algorithm (like RSA), Bob can use his private key to decrypt Alice's message. Most importantly, only Bob—because no one will ever get their hands on Bob's private key—can decrypt Alice's message....
