d2i_X509_REQ, i2d_X509_REQ, d2i_X509_REQ_bio, d2i_X509_REQ_fp, i2d_X509_REQ_bio, i2d_X509_REQ_fp - PKCS#10 certificate request functions.
X509_REQ *d2i_X509_REQ(X509_REQ **a, const unsigned char **pp, long length);
int i2d_X509_REQ(X509_REQ *a, unsigned char **pp);
X509_REQ *d2i_X509_REQ_bio(BIO *bp, X509_REQ **x);
X509_REQ *d2i_X509_REQ_fp(FILE *fp, X509_REQ **x);
int i2d_X509_REQ_bio(BIO *bp, X509_REQ *x);
int i2d_X509_REQ_fp(FILE *fp, X509_REQ *x);
These functions decode and encode a PKCS#10 certificate request.
Othewise these behave in a similar way to d2i_X509() and i2d_X509() described in the d2i_X509(3) manual page.

x509 - X.509 certificate handling
A X.509 certificate is a structured grouping of information about an individual, a device, or anything one can imagine. A X.509 CRL
(certificate revocation list) is a tool to help determine if a certificate is still valid. The exact definition of those can be found in
the X.509 document from ITU-T, or in RFC3280 from PKIX. In OpenSSL, the type X509 is used to express such a certificate, and the type
X509_CRL is used to express a CRL.
A related structure is a certificate request, defined in PKCS#10 from RSA Security, Inc, also reflected in RFC2896. In OpenSSL, the type
X509_REQ is used to express such a certificate request.
To handle some complex parts of a certificate, there are the types X509_NAME (to express a certificate name), X509_ATTRIBUTE (to express a
certificate attributes), X509_EXTENSION (to express a certificate extension) and a few more.
Finally, there's the supertype X509_INFO, which can contain a CRL, a certificate and a corresponding private key.
X509_..., d2i_X509_... and i2d_X509_... handle X.509 certificates, with some exceptions, shown below.
X509_CRL_..., d2i_X509_CRL_... and i2d_X509_CRL_... handle X.509 CRLs.
X509_REQ_..., d2i_X509_REQ_... and i2d_X509_REQ_... handle PKCS#10 certificate requests.
X509_NAME_... handle certificate names.
X509_ATTRIBUTE_... handle certificate attributes.
X509_EXTENSION_... handle certificate extensions.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.

Hey gang, I have a list of times I need to sum up. This list can vary from a few to a few thousand entries.

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
