  12. .Sh DESCRIPTION
    13. 

  13. .Nm
    14. 

  14. is a low-level utility for transforming raw, PEM-encoded RSA secret
    15. 

  15. keys into OpenPGP-formatted certificates.  The generated certificates
    16. 

  16. include the secret key material, so they should be handled carefully.
    17. 

  17. .Pp
    18. 

  18. It works as an element within a pipeline: feed it the raw key on
    19. 

  19. stdin, supply the desired User ID as a command line argument.  Note
    20. 

  20. that you may need to quote the string to ensure that it is entirely in
    21. 

  21. a single argument.
    22. 

  22. .Pp
    23. 

  23. Other choices about how to generate the new OpenPGP certificate are
    24. 

  24. governed by environment variables.
    25. 

  25. .Sh ENVIRONMENT
    26. 

  26. The following environment variables influence the behavior of
    27. 

  27. .Nm :
    28. 

  28. .Pp
    29. 

  29. .ti 3
    30. 

  30. \fBPEM2OPENPGP_TIMESTAMP\fP controls the timestamp (measured in
    31. 

  31. seconds since the UNIX epoch) indicated as the creation time (a.k.a
    32. 

  32. "not valid before") of the generated certificate.  By default,
    33. 

  33. .Nm
    34. 

  34. uses the current time.
    35. 

  35. .Pp
    36. 

  36. .ti 3
    37. 

  37. \fBPEM2OPENPGP_USAGE_FLAGS\fP should contain a comma-separated list of
    38. 

  38. valid OpenPGP usage flags (see section 5.2.3.21 of RFC 4880 for what
    39. 

  39. these mean).  The available choices are: certify, sign, encrypt_comms,
    40. 

  40. encrypt_storage, encrypt (this means both encrypt_comms and
    41. 

  41. encrypt_storage), authenticate, split, shared.  By default, 
    42. 

  42. .Nm
    43. 

  43. only sets the certify flag.
    44. 

  44. .Pp
    45. 

  45. .ti 3
    46. 

  46. \fBPEM2OPENPGP_EXPIRATION\fP sets an expiration (measured in seconds
    47. 

  47. after the creation time of the key) in each self-signature packet.  By
    48. 

  48. default, no expiration subpacket is included.
    49. 

  49. .Pp
    50. 

  50. .ti 3
    51. 

  51. \fBPEM2OPENPGP_NEWKEY\fP indicates that
    52. 

  52. .Nm
    53. 

  53. should ignore stdin, and instead generate a new key internally and
    54. 

  54. build the certificate based on this new key.  Set this variable to the
    55. 

  55. number of bits for the new key (e.g. 2048).  By default (when this is
    56. 

  56. unset), 
    57. 

  57. .Nm
    58. 

  58. will read the key from stdin.

  63. .Sh BUGS
    64. 

  64. Only handles RSA keys at the moment.  It would be nice to handle DSA
    65. 

  65. keys as well.
    66. 

  66. .Pp
    67. 

  67. Currently only creates certificates with a single User ID.  Should be
    68. 

  68. able to create certificates with multiple User IDs.
    69. 

  69. .Pp
    70. 

  70. Currently only accepts unencrypted RSA keys.  It should be able to
    71. 

  71. deal with passphrase-locked key material.
    72. 

  72. .Pp
    73. 

  73. Currently outputs OpenPGP certificates with cleartext secret key
    74. 

  74. material.  It would be good to be able to lock the output with a
    75. 

  75. passphrase.
