+
+=head1 DESCRIPTION
+
+RSA is vulnerable from timing attacks. In a setup where attackers can
+measure the time of RSA decryption or signature operations, blinding
+must be used to protect the RSA operation from that attack.
+
+RSA_blinding_on() turns blinding on for key B<rsa> and generates a
+random blinding factor. B<ctx> is B<NULL> or a pre-allocated and
+initialized B<BN_CTX>. The random number generator must be seeded
+prior to calling RSA_blinding_on().
+
+RSA_blinding_off() turns blinding off and frees the memory used for
+the blinding factor.

+
+=head1 DESCRIPTION
+
+RSA_generate_key() generates a key pair and returns it in a newly
+allocated B<RSA> structure. The pseudo-random number generator must
+be seeded prior to calling RSA_generate_key().
+
+The modulus size will be B<num> bits, and the public exponent will be
+B<e>. Key sizes with B<num> E<lt> 1024 should be considered insecure.
+The exponent is an odd number, typically 3 or 65535.
+
+A callback function may be used to provide feedback about the
+progress of the key generation. If B<callback> is not B<NULL>, it
+will be called as follows:
+
+=over 4
+

+
+While a random prime number is generated, it is called as
+described in L<BN_generate_prime(3)>.
+
+=item *
+
+When the n-th randomly generated prime is rejected as not
+suitable for the key, B<callback(2, n, cb_arg)> is called.
+
+=item *
+
+When a random p has been found with p-1 relatively prime to B<e>,
+it is called as B<callback(3, 0, cb_arg)>.
+
+=back
+
+The process is then repeated for prime q with B<callback(3, 1, cb_arg)>.
+
+=head1 RETURN VALUES
+
+If key generation fails, RSA_generate_key() returns B<NULL>; the
+error codes can be obtained by ERR_get_error(3).

+
+The RSA_padding_xxx_xxx() functions are called from the RSA encrypt,

+

+B<tlen> bytes and stores the result at B<to>. An error occurs if B<fl>

+An B<RSA_METHOD> specifies the functions that OpenSSL uses for RSA

+Initially, the default is to use the OpenSSL internal implementation,
+unless OpenSSL was configured with the C<rsaref> or C<-DRSA_NULL>
+options. RSA_PKCS1_SSLeay() returns a pointer to that method.
+
+RSA_PKCS1_RSAref() returns a pointer to a method that uses the RSAref
+library. This is the default method in the C<rsaref> configuration;
+the function is not available in other configurations.
+RSA_null_method() returns a pointer to a method that does not support
+the RSA transformation. It is the default if OpenSSL is compiled with
+C<-DRSA_NULL>. These methods may be useful in the USA because of a

+RSA_get_method() returns a pointer to the method currently selected

+
+RSA_flags() returns the B<flags> that are set for B<rsa>'s current method.

+RSA_sign_ASN1_OCTET_STRING, RSA_verify_ASN1_OCTET_STRING - RSA signatures
+
+=head1 SYNOPSIS
+
+ #include <openssl/rsa.h>
+
+ int RSA_sign_ASN1_OCTET_STRING(int dummy, unsigned char *m,
+ unsigned int m_len, unsigned char *sigret, unsigned int *siglen,
+ RSA *rsa);
+
+ int RSA_verify_ASN1_OCTET_STRING(int dummy, unsigned char *m,
+ unsigned int m_len, unsigned char *sigbuf, unsigned int siglen,
+ RSA *rsa);
+
+=head1 DESCRIPTION
+
+RSA_sign_ASN1_OCTET_STRING() signs the octet string B<m> of size
+B<m_len> using the private key B<rsa> represented in DER using PKCS #1
+padding. It stores the signature in B<sigret> and the signature size
+in B<siglen>. B<sigret> must point to B<RSA_size(rsa)> bytes of
+memory.
+
+B<dummy> is ignored.
+
+The random number generator must be seeded prior to calling RSA_sign_ASN1_OCTET_STRING().
+
+RSA_verify_ASN1_OCTET_STRING() verifies that the signature B<sigbuf>
+of size B<siglen> is the DER representation of a given octet string
+B<m> of size B<m_len>. B<dummy> is ignored. B<rsa> is the signer's
+public key.
+
+=head1 RETURN VALUES
+
+RSA_sign_ASN1_OCTET_STRING() returns 1 on success, 0 otherwise.
+RSA_verify_ASN1_OCTET_STRING() returns 1 on successful verification, 0
+otherwise.
+
+The error codes can be obtained by ERR_get_error(3).

+
+crypto - OpenSSL cryptographic library
+
+=head1 SYNOPSIS
+
+=head1 DESCRIPTION
+
+The OpenSSL B<crypto> library implements a wide range of cryptographic
+algorithms used in various Internet standards. The services provided
+by this library are used by the OpenSSL implementations of SSL, TLS
+and S/MIME, and they have also been used to implement SSH, OpenPGP, and
+other cryptographic standards.
+
+=head1 OVERVIEW
+
+B<libcrypto> consists of a number of sub-libraries that implement the
+individual algorithms.
+
+The functionality includes symmetric encryption, public key
+cryptography and key agreement, certificate handling, cryptographic
+hash functions and a cryptographic pseudo-random number generator.

+
+=head1 DESCRIPTION
+
+These functions implement RSA public key encryption and signatures
+as defined in PKCS #1 v2.0 [RFC 2437].
+
+The B<RSA> structure consists of several BIGNUM components. It can
+contain public as well as private RSA keys:
+
+ struct
+ {
+ BIGNUM *n; // public modulus
+ BIGNUM *e; // public exponent
+ BIGNUM *d; // private exponent
+ BIGNUM *p; // secret prime factor
+ BIGNUM *q; // secret prime factor
+ BIGNUM *dmp1; // d mod (p-1)
+ BIGNUM *dmq1; // d mod (q-1)
+ BIGNUM *iqmp; // q^-1 mod p
+ // ...
+ };
+ RSA
+
+In public keys, the private exponent and the related secret values are
+B<NULL>.
+
+B<dmp1>, B<dmq1> and B<iqmp> may be B<NULL> in private keys, but the
+RSA operations are much faster when these values are available.
+
+=head1 PATENTS
+
+RSA is covered by a US patent which expires in September 2000.
