Nondestructively reads a BER object from this string.

Destructively reads a BER object from the string.
# File lib/net/ber/core_ext/string.rb, line 51 def read_ber!(syntax = nil) io = StringIO.new(self) result = io.read_ber(syntax) self.slice!(0...io.pos) return result end
Converts a string to a BER string. Universal octet-strings are tagged with 0x04, but other values are possible depending on the context, so we let the caller give us one.
User code should call either to_ber_application_string or to_ber_contextspecific.
# File lib/net/ber/core_ext/string.rb, line 13 def to_ber(code = 0x04) raw_string = raw_utf8_encoded [code].pack('C') + raw_string.length.to_ber_length_encoding + raw_string end
Creates an application-specific BER string encoded value with the provided syntax code value.
# File lib/net/ber/core_ext/string.rb, line 32 def to_ber_application_string(code) to_ber(0x40 + code) end
Creates a context-specific BER string encoded value with the provided syntax code value.
# File lib/net/ber/core_ext/string.rb, line 39 def to_ber_contextspecific(code) to_ber(0x80 + code) end
