Sample Public Key Blob
The following hex dump shows a sample public key blob, generated by the
Microsoft RSA Base Provider. This contains a key exchange public key.
0x00000000 06 02 00 00 00 a4 00 00 ........
0x00000008 52 53 41 31 00 02 00 00 RSA1....
0x00000010 01 00 01 00 e1 94 84 7a .......z
0x00000018 27 4c 7b da db c5 99 dd 'L{.....
0x00000020 ed 20 1a b8 66 44 21 dc . ..fD!.
0x00000028 10 e5 ee 48 62 39 ae 8f ...Hb9..
0x00000030 cf 17 81 f0 37 8b b5 46 ....7..F
0x00000038 a9 65 b7 4e 75 83 84 4e .e.Nu..N

0x00000048 09 ec c2 30 96 f8 27 2b ...0..'+
0x00000050 33 cf a4 be 3...
Notice that the BLOBHEADER and RSAPUBKEY structures have been assigned the following values, and the last 64 bytes of
the blob contain the public key's modulus data.
blobheader.bType = PUBLICKEYBLOB; // 0x06
blobheader.bVersion = CUR_BLOB_VERSION; // 0x02
blobheader.Reserved = 0; // 0x0000
blobheader.aiKeyAlg = CALG_RSA_KEYX; // 0x0000a400
rsapubkey.magic = 0x31415352; // "RSA1"
rsapubkey.bitlen = 512; // 0x00000200
rsapubkey.pubexp = 65537; // 0x00010001
When filling in the BLOBHEADER structure, your code should place zero in the Reserved field.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
