Overview

ASN.1 Octet String

An OCTET STRINT may contain another primtive object:

os = OctetString.new
int = Integer.new
int.value = 12
os.value = int
os.to_der   # => DER string with INTEGER in OCTET STRING

Instance Method Details

#der_to_value(der, ber: false) ⇒ void

This method returns an undefined value.

Make string value from der string. Force encoding to UTF-8

Parameters:

  • der (String)
  • ber (::Boolean) (defaults to: false)

Since:

  • 0.15.0 Handle ENCODING constant, if defined by subclass
