  2. =head1 NAME
  3. openssl-pkeyparam,
  4. pkeyparam - public key algorithm parameter processing tool
  5. =head1 SYNOPSIS
  6. B<openssl> B<pkeyparam>
  7. [B<-help>]
  8. [B<-in filename>]
  9. [B<-out filename>]
  10. [B<-text>]
  11. [B<-noout>]
  12. [B<-engine id>]
  13. [B<-check>]
  14. =head1 DESCRIPTION
  15. The B<pkeyparam> command processes public key algorithm parameters.
  16. They can be checked for correctness and their components printed out.
  17. =head1 OPTIONS
  18. =over 4
  19. =item B<-help>
  20. Print out a usage message.
  21. =item B<-in filename>
  22. This specifies the input filename to read parameters from or standard input if
  23. this option is not specified.
  24. =item B<-out filename>
  25. This specifies the output filename to write parameters to or standard output if
  26. this option is not specified.
  27. =item B<-text>
  28. Prints out the parameters in plain text in addition to the encoded version.
  29. =item B<-noout>
  30. Do not output the encoded version of the parameters.
  31. =item B<-engine id>
  32. Specifying an engine (by its unique B<id> string) will cause B<pkeyparam>
  33. to attempt to obtain a functional reference to the specified engine,
  34. thus initialising it if needed. The engine will then be set as the default
  35. for all available algorithms.
  36. =item B<-check>
  37. This option checks the correctness of parameters.
  38. =back
  39. =head1 EXAMPLE
  40. Print out text version of parameters:
  41. openssl pkeyparam -in param.pem -text
  42. =head1 NOTES
  43. There are no B<-inform> or B<-outform> options for this command because only
  44. PEM format is supported because the key type is determined by the PEM headers.
