If you mean an OID with just the value '1' that's illegal. If you mean an OID ending in 1.0 or just 1 with the same prefix then they do *NOT* have the same encoding. You can create these thing using the OpenSSL mini-ASN1 compiler in 0.9.8: openssl asn1parse -genstr OID:1.2.3.1.0 Steve. -- Dr Stephen N. Henson.
