Name
RSA_generate_key - generate RSA key pair
Creating an SSH Key Pair for User Authentication. The simplest way to generate a key pair is to run ssh-keygen without arguments. In this case, it will prompt for the file in which to store keys. Here's an example: klar (11:39) ssh-keygen Generating public/private rsa key pair. This is tool for generate ssh DSA key online and for free.The result of tool generation are ssh dsa private key and ssh dsa public key. Also it's called as ' generate ssh pair '. It will be two text area fileds - the first private key, the second public key. The RSA private key consists of the modulus n and the private exponent d. Only the owner of the key pair is allowed to see the private exponent. The modulus however is public. Private key B uses the Chinese Remainder Theorem (CRT) which decypts the ciphertext 4 times faster as private key A.
Synopsis
Description
That generates a 2048-bit RSA key pair, encrypts them with a password you provide and writes them to a file. You need to next extract the public key file. You will use this, for instance, on your web server to encrypt content so that it can only be read with the private key. RSA is an asymmetric encryption algorithm. With a given key pair, data that is encrypted with one key can only be decrypted by the other. This is useful for encrypting data between a large number of parties; only one key pair per person need exist. RSA is widely used across the internet with HTTPS.
RSA_generate_key() generates a key pair and returns it in a newly allocated RSA Generate pem from cert and key. structure. The pseudo-random number generatormust be seeded prior to calling RSA_generate_key().
The modulus size will be num bits, and the public exponent will be e. Key sizes with num < 1024 should be considered insecure. Theexponent is an odd number, typically 3, 17 or 65537.
A callback function may be used to provide feedback about the progress of the key generation. If callback is not NULL , it willbe called as follows:
• While a random prime number is generated, it is called as described in bn_generate_prime(3).• When the n-th randomly generated prime is rejected as not suitable for the key, callback(2, n, cb_arg) is called.
• When a random p has been found with p-1 relatively prime to e, it is called as callback(3, 0, cb_arg).
Return Value
If key generation fails, RSA_generate_key() returns NULL ; the error codes can be obtained byerr_get_error(3).
Bugs
callback(2, x, cb_arg) is used with two different meanings. Speedypc pro license key generator free download.
RSA_generate_key() goes into an infinite loop for illegal input values.
