decode_all (p1)
public
Similar to #decode with the
difference that #decode
expects one distinct value represented in der . #decode_all on the contrary
decodes a sequence of sequential BER/DER values lined up in der
and returns them as an array.
Example
ders = File . binread (' asn1data_seq ')
asn1_ary = OpenSSL :: ASN1 . decode_all ( ders ) Show source static VALUE
ossl_asn1_decode_all(VALUE self, VALUE obj)
{
VALUE ary, val;
unsigned char *p;
long len, tmp_len = 0, read = 0, offset = 0;
VALUE tmp;
obj = ossl_to_der_if_possible(obj);
tmp = rb_str_new4(StringValue(obj));
p = (unsigned char *)RSTRING_PTR(tmp);
len = RSTRING_LEN(tmp);
tmp_len = len;
ary = rb_ary_new();
while (tmp_len > 0) {
long tmp_read = 0;
val = ossl_asn1_decode0(&p, tmp_len, &offset, 0, 0, &tmp_read);
rb_ary_push(ary, val);
read += tmp_read;
tmp_len -= tmp_read;
}
RB_GC_GUARD(tmp);
int_ossl_decode_sanity_check(len, read, offset);
return ary;
