RSA證書說明

公鑰證書采用的是X509證書：

openssl asn1parse -in rsa_public_key.pem -strparse 18
0:d=0 hl=3 l= 137 cons: SEQUENCE
3:d=1 hl=3 l= 129 prim: INTEGER :CDF9E1C4973CBDA66644BB259F7FFB43AF0DC86F440400EB6ACF5734B1350D758DF78091BCA7BCEB30E8D8D47CADA0FACBD0BF13250C5110E49CF39B32642ECDA5B222D282A197DE1DED09749FC638617D8DF15179D935CAECBD9D38C6C5FF1E4EFDBBC6D69C28B69C19E4FA325A98C3B90863AFD7251438C93F12473C8FF94B
135:d=1 hl=2 l= 3 prim: INTEGER :010001

 

30 81 9F //30代表的是sequence數據段屬性
30 0D 06 09 2A 86 48 86 F7 0D 01 01 01 05 00
03 81 8D 00//03代表是bit string數據字段

30 81 89

02 81 81 //81表示長度域為1個字節，長度為0x81,代表的是n

38 C9 3F 12 47 3C 8F F9 4B
02 03 01 00 01//直接用長度表示，03表示有3個字節，02代表的是整值數據類型，010001數據代表的是e值

長度說明：如果長度小於127，那么用一個字節表示，如果長度大於127，大於01111111，后續字節第一位為1表示長度域有幾個字節

一般情況，公鑰證書采用的是509的格式，但是私鑰證書采用的格式不一樣，一般采用的是pcks1的格式，
