Indent some of the code examples.

* How do I read or write a DER encoded buffer using the ASN1 functions?

You have two options. You can either use a memory BIO in conjunction

with the i2d_XXX_bio() or d2i_XXX_bio() functions or you can use the

i2d_XXX(), d2i_XXX() functions directly. Since these are often the

with the i2d_*_bio() or d2i_*_bio() functions or you can use the

i2d_*(), d2i_*() functions directly. Since these are often the

cause of grief here are some code fragments using PKCS7 as an example:

 unsigned char *buf, *p;
