Encryption signature.

The private key (without-pubin) can be used for encryption since it actually contains the public exponent. Note that RSA should not normally be used to encrypt data directly, but only to 'encapsulate' (RSA-KEM) or 'wrap' the key(s) used for symmetric encryption. But you mention you actually want to study signature.

The output of this process is called Digital Signature (DS) of A. Digital signature creation. Step-3 : Now sender A sends the digital signature (DS) along with the original message (M) to B. Transmission of original message and digital signature simultaneously.

Digital Signature Encryption. Sending an encrypted message is a safer choice than sending plaintexts. In public-key encryption, the sender’s public key is openly available and anyone can spoof their identity to send encrypted messages. The best way out of this is to use a Digital Signature along with encrypted messages.

The process works by using algorithms and cryptographic keys to encrypt and decrypt data. Two common types of cryptography are symmetric (private key cryptography) and asymmetric (public key cryptography). The first uses a single key for encryption and decryption, while the latter utilizes a pair of keys, one public for encryption and a private ...

Asymmetric and symmetric encryption are two primary techniques used to secure data. Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses …One small correction, "HS256 (HMAC with SHA-256), on the other hand, is a symmetric algorithm" - HMAC does not utilize a symmetric-key algorithm (which would allow you to encrypt and decrypt the signature by its definition).
