I'm an italian young engineer and I'm working on new software project that wuold want to use yours openssl library to realize an encryption/decryption protocol to use for downloading updates from a server. I try to find on web some informations, but i'm not able to understand about the sizes. I explain better. I've to know, more exactly, how to calculate the dimension of an encrypted text after an encryption with a private key with an RSA protocol.. and so, also the dimension of a decrypted text after an decryption with a public key. I don't know if you can help me.. I would appreciate any help or suggestion. Sorry for disturb and thanks for all your work. -- Alfonso Coscione ---------------------------------------------------------------------------- --------------- "before giving good advice, we must give good examples..in life it takes consistency .. !!" ---------------------------------------------------------------------------- --------------- - Please respect the environment before printing this email unless absolutely necessary. - -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
