NAME
ASN1_buf_print —
pretty-print a byte array
SYNOPSIS
#include
<openssl/asn1.h>
int
ASN1_buf_print(BIO *bio_out,
const unsigned char *buf, size_t
buflen, int indent);
DESCRIPTION
ASN1_buf_print()
prints a hexadecimal representation of the first
buflen bytes from buf to
bio_out. Despite its name and the header file, this
function has nothing to do with ASN.1.
Each byte from buf is represented by two lower-case hexadecimal digits. Fifteen pairs of digits are printed per output line, or at most fifteen on the last output line. Every output line including the last one ends with a newline character. Every pair except the last is followed by a colon (‘:’). If indent is greater than zero, every output line is indented by indent space characters, but not by more than 64 characters.
RETURN VALUES
ASN1_buf_print() returns 1 if successful
or 0 if printing fails.

HISTORY
ASN1_buf_print() first appeared in OpenSSL
1.1.0 and has been available since OpenBSD 7.3.
