which is redundant. They are now in their own document. Also, in the name section, all the functions described shoud be enumerated. This will also make it much simpler to generate softlinks name like each function to man-pages containing the info.

=head1 NAME

|
|
|
BIO_f_base64 - base64 BIO filter
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/bio.h>
|
|
#include <openssl/evp.h>
|
|
|
|
BIO_METHOD * BIO_f_base64(void);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
BIO_f_base64() returns the base64 BIO method. This is a filter
|
|
BIO that base64 encodes any data written through it and decodes
|
|
any data read through it.
|
|
|
|
Base64 BIOs do not support BIO_gets() or BIO_puts().
|
|
|
|
BIO_flush() on a base64 BIO that is being written through is
|
|
used to signal that no more data is to be encoded: this is used
|
|
to flush the final block through the BIO.
|
|
|
|
The flag BIO_FLAGS_BASE64_NO_NL can be set with BIO_set_flags()
|
|
to encode the data all on one line or expect the data to be all
|
|
on one line.
|
|
|
|
=head1 NOTES
|
|
|
|
Because of the format of base64 encoding the end of the encoded
|
|
block cannot always be reliably determined.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
BIO_f_base64() returns the base64 BIO method.
|
|
|
|
=head1 EXAMPLES
|
|
|
|
Base64 encode the string "Hello World\n" and write the result
|
|
to standard output:
|
|
|
|
BIO *bio, *b64;
|
|
char message[] = "Hello World \n";
|
|
|
|
b64 = BIO_new(BIO_f_base64());
|
|
bio = BIO_new_fp(stdout, BIO_NOCLOSE);
|
|
bio = BIO_push(b64, bio);
|
|
BIO_write(bio, message, strlen(message));
|
|
BIO_flush(bio);
|
|
|
|
BIO_free_all(bio);
|
|
|
|
Read Base64 encoded data from standard input and write the decoded
|
|
data to standard output:
|
|
|
|
BIO *bio, *b64, bio_out;
|
|
char inbuf[512];
|
|
int inlen;
|
|
char message[] = "Hello World \n";
|
|
|
|
b64 = BIO_new(BIO_f_base64());
|
|
bio = BIO_new_fp(stdin, BIO_NOCLOSE);
|
|
bio_out = BIO_new_fp(stdout, BIO_NOCLOSE);
|
|
bio = BIO_push(b64, bio);
|
|
while((inlen = BIO_read(bio, inbuf, strlen(message))) > 0)
|
|
BIO_write(bio_out, inbuf, inlen);
|
|
|
|
BIO_free_all(bio);
|
|
|
|
=head1 BUGS
|
|
|
|
The ambiguity of EOF in base64 encoded data can cause additional
|
|
data following the base64 encoded block to be misinterpreted.
|
|
|
|
There should be some way of specifying a test that the BIO can perform
|
|
to reliably determine EOF (for example a MIME boundary).
