GENRSA(1)                           OpenSSL                          GENRSA(1)

NAME
       genrsa - generate an RSA private key

SYNOPSIS
       openssl genrsa [-help] [-out filename] [-passout arg] [-aes128]
       [-aes192] [-aes256] [-aria128] [-aria192] [-aria256] [-camellia128]
       [-camellia192] [-camellia256] [-des] [-des3] [-idea] [-f4] [-3] [-rand
       file(s)] [-engine id] [numbits]

DESCRIPTION
       The genrsa command generates an RSA private key.

OPTIONS
       -help
           Print out a usage message.

       -out filename
           Output  the  key  to  the  specified  file. If this argument is not
           specified then standard output is used.

       -passout arg
           the output file password source. For  more  information  about  the
           format of arg see the PASS PHRASE ARGUMENTS section in openssl(1).

       -aes128|-aes192|-aes256|-aria128|-aria192|-aria256|-camellia128|-camellia192|-camellia256|-des|-des3|-idea
           These  options encrypt the private key with specified cipher before
           outputting it. If none of these options is specified no  encryption
           is  used. If encryption is used a pass phrase is prompted for if it
           is not supplied via the -passout argument.

       -F4|-3
           the public exponent to use, either  65537  or  3.  The  default  is
           65537.

       -rand file(s)
           a  file  or  files  containing  random data used to seed the random
           number generator, or an EGD  socket  (see  RAND_egd(3)).   Multiple
           files can be specified separated by an OS-dependent character.  The
           separator is ; for MS-Windows, , for OpenVMS, and : for all others.

       -engine id
           specifying an engine (by its unique id string) will cause genrsa to
           attempt  to  obtain a functional reference to the specified engine,
           thus initialising it if needed. The engine will then be set as  the
           default for all available algorithms.

       numbits
           the  size  of the private key to generate in bits. This must be the
           last option specified. The default is 2048.

NOTES
       RSA private key generation essentially involves the generation  of  two
       prime  numbers.  When  generating a private key various symbols will be
       output to indicate the progress of the generation. A . represents  each
       number  which  has  passed  an initial sieve test, + means a number has
       passed a single round of the Miller-Rabin  primality  test.  A  newline
       means that the number has passed all the prime tests (the actual number
       depends on the key size).

       Because key generation is a random process the time taken to generate a
       key may vary somewhat.

BUGS
       A  quirk  of  the prime generation algorithm is that it cannot generate
       small primes. Therefore the number of bits should not be less that  64.
       For  typical  private  keys  this  will not matter because for security
       reasons they will be much larger (typically 1024 bits).
