expands to the set of declarations shown in
the next four lines of the synopsis.
These routines convert between local instances of ASN1 datatypes and
the PEM encoding. For more information on the templates, see
ASN1_ITEM(3). For more information on the lower-level routines used
by the functions here, see PEM_read(3).
PEM_read_TYPE() reads a PEM-encoded object of TYPE from the file fp
and returns it. The cb and u parameters are as described in
PEM_read_bio_TYPE() is similar to PEM_read_TYPE() but reads from the BIO bp.
PEM_write_TYPE() writes the PEM encoding of the object a to the file fp.
PEM_write_bio_TYPE() similarly writes to the BIO bp.
These functions make no assumption regarding the pass phrase received from the
It will simply be treated as a byte sequence.
return a pointer to an allocated
object, which should be released by calling TYPE_free()
, or NULL
PEM_write_TYPE() and PEM_write_bio_TYPE() return the number of bytes written
or zero on error.
