-.Sh NAME
-.Nm BIO_f_base64
-.\" .Nm EVP_ENCODE_LENGTH and
-.\" .Nm EVP_DECODE_LENGTH are intentionally undocumented
-.\" because they are internal implementation details of BIO_f_base64(3)

-.Nd base64 BIO filter
-.Sh SYNOPSIS
-.In openssl/bio.h
-.In openssl/evp.h
-.Ft const BIO_METHOD *
-.Fo BIO_f_base64
-.Fa void
-.Fc
-.Sh DESCRIPTION
-.Fn 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.
-.Pp
-Base64 BIOs do not support
-.Xr BIO_gets 3
-or
-.Xr BIO_puts 3 .
-.Pp
-.Xr BIO_flush 3
-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.
-.Pp
-To encode the data all on one line and to expect the data to be all
-on one line, initialize the base64 BIO as follows:
-.Bd -literal -offset indent
-BIO *b64 = BIO_new(BIO_f_base64());
-BIO_set_flags(b64, BIO_FLAGS_BASE64_NO_NL);
-.Ed
-.Sh RETURN VALUES
-.Fn BIO_f_base64
-returns the base64 BIO method.
-.Pp
-When called on a base64 BIO object,
-.Xr BIO_method_type 3
-returns the constant
-.Dv BIO_TYPE_BASE64
-and
-.Xr BIO_method_name 3
-returns a pointer to the static string
-.Qq base64 encoding .
-.Sh EXAMPLES
-Base64 encode the string "hello, world\en"
-and write the result to standard output:
-.Bd -literal -offset indent
-BIO *bio, *b64;
-char message[] = "hello, world\en";
-
-b64 = BIO_new(BIO_f_base64());
-bio = BIO_new_fp(stdout, BIO_NOCLOSE);
-BIO_push(b64, bio);
-BIO_write(b64, message, strlen(message));
-BIO_flush(b64);
-
-BIO_free_all(b64);
-.Ed
-.Pp
-Read Base64-encoded data from standard input
-and write the decoded data to standard output:
-.Bd -literal -offset indent
-BIO *bio, *b64, *bio_out;
-char inbuf[512];
-int inlen;
-
-b64 = BIO_new(BIO_f_base64());
-bio = BIO_new_fp(stdin, BIO_NOCLOSE);
-bio_out = BIO_new_fp(stdout, BIO_NOCLOSE);
-BIO_push(b64, bio);
-while((inlen = BIO_read(b64, inbuf, 512)) > 0)
-        BIO_write(bio_out, inbuf, inlen);
-
-BIO_flush(bio_out);
-BIO_free_all(b64);

-.Sh SEE ALSO
-.Xr BIO_new 3 ,
-.Xr EVP_EncodeInit 3
-.Sh HISTORY
-.Fn BIO_f_base64
-first appeared in SSLeay 0.6.5 and has been available since
-.Ox 2.4 .
-.Sh BUGS
-The ambiguity of EOF in base64-encoded data can cause additional
-data following the base64-encoded block to be misinterpreted.
-.Pp
-There should be some way of specifying a test that the BIO can perform
-to reliably determine EOF (for example a MIME boundary).
