Nowadays, RSA is the well-known cryptosystem which supports most of electronic commercial communications. RSA is working on the base of multiplication of two prime numbers. Currently different kinds of attacks have identified against RSA by cryptanalysis. This paper has shown that regardless to the size of secret key and public key, it is possible to decrypt one cipher text by different secret keys RSA algorithm and in excellent condition, there are two similar key at least available in domain of two prime numbers multiplication.
