The requirement for public/private keys in this system is for a slightly different purpose - whereas in RSA, a key is needed so anyone can encrypt, in DSA a key is needed so anyone can verify. In RSA, the private key allows decryption; in DSA, the private key allows signature creation. DSA Private Key is used for generating Signature file. Dec 11, 2007  I need to generate an RSA key pair on the card based on pre-defined P, Q and public exponent. The KeyPair specs syas that if the public exponent is pre-initialized it will be retained. /autocad-2009-key-generator-download.html. All other values are overwritten though (I checked with a test applet on jcop41). So two questions: 1. Do you know of any card that can also retain p and q.

RSA (Rivest–Shamir–Adleman) is one of the first public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and distinct from the decryption key which is kept secret (private). In RSA, this asymmetry is based on the practical difficulty of factoring the product of two large prime numbers, the 'factoring problem'. RSA (Rivest–Shamir–Adleman) is one of the first public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and distinct from the decryption key which is kept secret (private). The following steps are involved in generating RSA keys − Create two large prime numbers namely p and q. The product of these numbers will be called n, where n= p.q. Generate a random number which is relatively prime with (p-1) and (q-1). Let the number be called as e. Calculate the modular inverse of e. The calculated inverse will be called.

Generating RSA keys

The following steps are involved in generating RSA keys −

  • Create two large prime numbers namely p and q. The product of these numbers will be called n, where n= p*q

  • Generate a random number which is relatively prime with (p-1) and (q-1). Let the number be called as e.

  • Calculate the modular inverse of e. The calculated inverse will be called as d.

Algorithms for generating RSA keys

We need two primary algorithms for generating RSA keys using Python − Cryptomath module and Rabin Miller module. Witcher 2 activation key generator.
