Signeerasi

Signeerasi is a term that refers to the process of signing a document or message using a cryptographic key. This process ensures the authenticity and integrity of the document, as it can be verified by others who possess the corresponding public key. Signeerasi is commonly used in digital communications, software distribution, and secure transactions to prevent tampering and to confirm the identity of the sender. The most widely used signeerasi algorithms include RSA, DSA, and ECDSA, each offering different levels of security and efficiency. The signeerasi process typically involves hashing the document to create a fixed-size string, encrypting this hash with the private key, and then appending the resulting signeerasi to the document. The recipient can then use the sender's public key to decrypt the signeerasi and verify that the document has not been altered since it was signeerasi. This process is fundamental to modern cryptography and is essential for securing digital communications and transactions.
