80 specific encoding rules, examples, and comments about their
241 String types can be viewed, for the purposes of encoding, as
246 length encoding (see Section 3).
299 For purposes of encoding, an implicitly tagged type is
329 primitive, definite-length encoding; constructed, definite-
330 length encoding; and constructed, indefinite-length
331 encoding. Simple non-string types employ the primitive,
339 In each method, the BER encoding has three or four parts:
360 The three methods of encoding are described in the following

520 DER encoding. The focus of the encodings is primarily on the
572 BER encoding. Primitive or constructed, depending on the

1061 Example: The first octet of the BER encoding of RSA Data
1063 2a16. The encoding of 840 = 6 * 128 + 4816 is 86 48 and the
1064 encoding of 113549 = 6 * 1282 + 7716 * 128 + d16 is 86 f7
