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; + + 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, 512)) > 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). + +=head1 SEE ALSO + +TBA -- cgit v1.2.3
