#include <openssl/asn1.h> int ASN1_STRING_print_ex(BIO *out, const ASN1_STRING *str, unsigned long flags); int ASN1_STRING_print_ex_fp(FILE *fp, const ASN1_STRING *str, unsigned long flags); int ASN1_STRING_print(BIO *out, const ASN1_STRING *str); const char *ASN1_tag2str(int tag);
DESCRIPTIONThese functions output an
ASN1_STRING_print_ex() outputs str to out, the format is determined by the options flags. ASN1_STRING_print_ex_fp() is identical except it outputs to fp instead.
ASN1_STRING_print() prints str to out but using a different format to ASN1_STRING_print_ex(). It replaces unprintable characters (other than
ASN1_tag2str() returns a human-readable name of the specified
NOTESASN1_STRING_print() is a legacy function which should be avoided in new applications.
Although there are a large number of options frequently
The complete set of supported options for flags is listed below.
Various characters can be escaped. If
Escaping takes several forms.
If the character being escaped is a 16 bit character then the form ``\UXXXX'' is used using exactly four characters for the hex representation. If it is 32 bits then ``\WXXXXXXXX'' is used using eight characters of its hex representation. These forms will only be used if
Printable characters are normally escaped using the backslash '\' character. If
The content of a string instead of being interpreted can be ``dumped'': this just outputs the value of the string using the form #XXXX using hex format for each octet.
Normally non character string types (such as
When a type is dumped normally just the content octets are printed, if
