148 \& int ASN1_STRING_print_ex(BIO *out, ASN1_STRING *str, unsigned long flags);

150 \& int ASN1_STRING_print(BIO *out, ASN1_STRING *str);
153 .IX Header "DESCRIPTION"
154 These functions output an \fB\s-1ASN1_STRING\s0\fR structure. \fB\s-1ASN1_STRING\s0\fR is used to
155 represent all the \s-1ASN1\s0 string types.
157 \&\fIASN1_STRING_print_ex()\fR outputs \fBstr\fR to \fBout\fR, the format is determined by
158 the options \fBflags\fR. \fIASN1_STRING_print_ex_fp()\fR is identical except it outputs
161 \&\fIASN1_STRING_print()\fR prints \fBstr\fR to \fBout\fR but using a different format to
162 \&\fIASN1_STRING_print_ex()\fR. It replaces unprintable characters (other than \s-1CR, LF\s0)
166 \&\fIASN1_STRING_print()\fR is a legacy function which should be avoided in new applications.
168 Although there are a large number of options frequently \fB\s-1ASN1_STRFLGS_RFC2253\s0\fR is
169 suitable, or on \s-1UTF8\s0 terminals \fB\s-1ASN1_STRFLGS_RFC2253 &\s0 ~ASN1_STRFLGS_ESC_MSB\fR.
171 The complete set of supported options for \fBflags\fR is listed below.
173 Various characters can be escaped. If \fB\s-1ASN1_STRFLGS_ESC_2253\s0\fR is set the characters
174 determined by \s-1RFC2253\s0 are escaped. If \fB\s-1ASN1_STRFLGS_ESC_CTRL\s0\fR is set control
175 characters are escaped. If \fB\s-1ASN1_STRFLGS_ESC_MSB\s0\fR is set characters with the
176 \&\s-1MSB\s0 set are escaped: this option should \fBnot\fR be used if the terminal correctly
177 interprets \s-1UTF8\s0 sequences.
179 Escaping takes several forms.
181 If the character being escaped is a 16 bit character then the form \*(L"\eUXXXX\*(R" is used
182 using exactly four characters for the hex representation. If it is 32 bits then
183 \&\*(L"\eWXXXXXXXX\*(R" is used using eight characters of its hex representation. These forms
184 will only be used if \s-1UTF8\s0 conversion is not set (see below).
186 Printable characters are normally escaped using the backslash '\e' character. If
187 \&\fB\s-1ASN1_STRFLGS_ESC_QUOTE\s0\fR is set then the whole string is instead surrounded by
188 double quote characters: this is arguably more readable than the backslash
189 notation. Other characters use the \*(L"\eXX\*(R" using exactly two characters of the hex
192 If \fB\s-1ASN1_STRFLGS_UTF8_CONVERT\s0\fR is set then characters are converted to \s-1UTF8\s0
193 format first. If the terminal supports the display of \s-1UTF8\s0 sequences then this
194 option will correctly display multi byte characters.
196 If \fB\s-1ASN1_STRFLGS_IGNORE_TYPE\s0\fR is set then the string type is not interpreted at
197 all: everything is assumed to be one byte per character. This is primarily for
198 debugging purposes and can result in confusing output in multi character strings.
200 If \fB\s-1ASN1_STRFLGS_SHOW_TYPE\s0\fR is set then the string type itself is printed out
201 before its value (for example \*(L"\s-1BMPSTRING\*(R"\s0), this actually uses \fIASN1_tag2str()\fR.
203 The content of a string instead of being interpreted can be \*(L"dumped\*(R": this just
204 outputs the value of the string using the form #XXXX using hex format for each
207 If \fB\s-1ASN1_STRFLGS_DUMP_ALL\s0\fR is set then any type is dumped.
209 Normally non character string types (such as \s-1OCTET STRING\s0) are assumed to be
210 one byte per character, if \fB\s-1ASN1_STRFLGS_DUMP_UNKNOWN\s0\fR is set then they will
213 When a type is dumped normally just the content octets are printed, if
214 \&\fB\s-1ASN1_STRFLGS_DUMP_DER\s0\fR is set then the complete encoding is dumped
215 instead (including tag and length octets).
217 \&\fB\s-1ASN1_STRFLGS_RFC2253\s0\fR includes all the flags required by \s-1RFC2253.\s0 It is
219 \s-1ASN1_STRFLGS_ESC_2253\s0 | \s-1ASN1_STRFLGS_ESC_CTRL\s0 | \s-1ASN1_STRFLGS_ESC_MSB\s0 |
220 \s-1ASN1_STRFLGS_UTF8_CONVERT\s0 | \s-1ASN1_STRFLGS_DUMP_UNKNOWN ASN1_STRFLGS_DUMP_DER\s0
