While stereotyped repetitions are frowned upon in literature, they serve a useful purpose in manual pages, because it is easier for the user to find certain information if it is always presented in the same way. For that reason, this commit harmonizes the varying formulations in the HISTORY section about which functions, flags, etc. were added in which OpenSSL version. It also attempts to make the pod files more grep friendly by avoiding to insert line breaks between the symbol names and the corresponding version number in which they were introduced (wherever possible). Some punctuation and typographical errors were fixed on the way. Reviewed-by: Tim Hudson <tjh@openssl.org> (Merged from https://github.com/openssl/openssl/pull/7854)

=head1 NAME
|
|
|
|
RSA_size, RSA_bits, RSA_security_bits - get RSA modulus size or security bits
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/rsa.h>
|
|
|
|
int RSA_size(const RSA *rsa);
|
|
|
|
int RSA_bits(const RSA *rsa);
|
|
|
|
int RSA_security_bits(const RSA *rsa)
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
RSA_size() returns the RSA modulus size in bytes. It can be used to
|
|
determine how much memory must be allocated for an RSA encrypted
|
|
value.
|
|
|
|
RSA_bits() returns the number of significant bits.
|
|
|
|
B<rsa> and B<rsa-E<gt>n> must not be B<NULL>.
|
|
|
|
RSA_security_bits() returns the number of security bits of the given B<rsa>
|
|
key. See L<BN_security_bits(3)>.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
RSA_size() returns the size of modulus in bytes.
|
|
|
|
DSA_bits() returns the number of bits in the key.
|
|
|
|
RSA_security_bits() returns the number of security bits.
|
|
|
|

|
|
|
|
=head1 HISTORY
|
|
|
|
The RSA_bits() function was added in OpenSSL 1.1.0.
