B<ASN1_STRING> is used to -represent all the ASN1 string types. - -ASN1_STRING_print_ex() outputs B<str> to B<out>, the format is determined by -the options B<flags>. ASN1_STRING_print_ex_fp() is identical except it outputs -to B<fp> instead. - -ASN1_STRING_print() prints B<str> to B<out> but using a different format to -ASN1_STRING_print_ex(). It replaces unprintable characters (other than CR, LF) -with '.'. - -=head1 NOTES - -ASN1_STRING_print() is a legacy function which should be avoided in new applications. - -Although there are a large number of options frequently B<ASN1_STRFLGS_RFC2253> is -suitable, or on UTF8 terminals B<ASN1_STRFLGS_RFC2253 & ~ASN1_STRFLGS_ESC_MSB>. - -The complete set of supported options for B<flags> is listed below. - -Various characters can be escaped. If B<ASN1_STRFLGS_ESC_2253> is set the characters -determined by RFC2253 are escaped. If B<ASN1_STRFLGS_ESC_CTRL> is set control -characters are escaped. If B<ASN1_STRFLGS_ESC_MSB> is set characters with the -MSB set are escaped: this option should B<not> be used if the terminal correctly -interprets UTF8 sequences. - -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 UTF8 conversion is not set (see below). - -Printable characters are normally escaped using the backslash '\' character. If -B<ASN1_STRFLGS_ESC_QUOTE> is set then the whole string is instead surrounded by -double quote characters: this is arguably more readable than the backslash -notation. Other characters use the "\XX" using exactly two characters of the hex -representation. - -If B<ASN1_STRFLGS_UTF8_CONVERT> is set then characters are converted to UTF8 -format first. If the terminal supports the display of UTF8 sequences then this -option will correctly display multi byte characters. - -If B<ASN1_STRFLGS_IGNORE_TYPE> is set then the string type is not interpreted at -all: everything is assumed to be one byte per character. This is primarily for -debugging purposes and can result in confusing output in multi character strings. - -If B<ASN1_STRFLGS_SHOW_TYPE> is set then the string type itself is printed out -before its value (for example "BMPSTRING"), this actually uses ASN1_tag2str(). - -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. - -If B<ASN1_STRFLGS_DUMP_ALL> is set then any type is dumped. - -Normally non character string types (such as OCTET STRING) are assumed to be -one byte per character, if B<ASN1_STRFLGS_DUMP_UNKNOWN> is set then they will -be dumped instead. - -When a type is dumped normally just the content octets are printed, if -B<ASN1_STRFLGS_DUMP_DER> is set then the complete encoding is dumped -instead (including tag and length octets). - -B<ASN1_STRFLGS_RFC2253> includes all the flags required by RFC2253. It is -equivalent to: - ASN1_STRFLGS_ESC_2253 | ASN1_STRFLGS_ESC_CTRL | ASN1_STRFLGS_ESC_MSB | - ASN1_STRFLGS_UTF8_CONVERT | ASN1_STRFLGS_DUMP_UNKNOWN ASN1_STRFLGS_DUMP_DER - -=head1 SEE ALSO - -L<X509_NAME_print_ex(3)|X509_NAME_print_ex(3)>, -L<ASN1_tag2str(3)|ASN1_tag2str(3)> - -=head1 HISTORY - -TBA - -=cut |
