Problems with rsa algorithm
Webb26 jan. 2015 · I want to encrypt and decrypt ASCII messages using an RSA algorithm written in assembly. I read that for security and efficiency reasons the encryption is normally not called character-wise but a number of characters is grouped and encrypted together (e.g. wikipedia says that 3 chars are grouped).

WebbThe Rivest-Shamir-Adleman (RSA) algorithm is the most widely accepted approach in asymmetric cryptography. Asymmetric cryptography means that one key is used to … WebbRSA used without padding may have some problems: The values m = 0 or m = 1 always produce ciphertexts equal to 0 or 1 respectively, due to the properties of exponentiation. When encrypting with small encryption exponents (e.g., e = 3) and small values of the m , the (non-modular) result of m e {\displaystyle m^{e}} may be strictly less than the …

In cryptography, the RSA problem summarizes the task of performing an RSA private-key operation given only the public key. The RSA algorithm raises a message to an exponent, modulo a composite number N whose factors are not known. Thus, the task can be neatly described as finding the e roots of an arbitrary number, modulo N. For large RSA key sizes (in excess of 1024 bits), no efficient method for solving this problem is known; if an efficient method is ever developed, it wo…

It is a public-key encryption technique used for secure data transmission especially over the internet. Transmitting confidential and sensitive data over the internet through this technology is safe due to its standard encryption method.
