I'm trying to understand the layout of the record in appendix B of the APG.

I have

Exists: CSNDKRR read PKDS2 PKDS rc 0 rs 0 No error found .

00000000 : 1F0001C2 00000000

**30**0001AA 002E00B0 ...B............ ........0.......

00000010 : 00000202 24000200 00000000 00000000 ................ ....¢...........

000001A0 : E75C6F4C C462E166 0F962B7A 897C92E4

000001B0 : CF25

**0400 00100000 0004>0400< 00000001 ****000001C0 : 0001**The 30 according to table 588 is

*RSA private key,*** 4096-bit** Modulus-Exponent format with AES-encrypted OPK. Internal and external formatThe 04 is (Table 597) is public ... the 0400 is the Public key modulus length in bits .... which is 1024

If I display it using the ISPF panels it gives

Algorithm: RSA Modulus (bits):

**1024 **which ties up with the public

My question is - Why is this called a 4096 ME when the Modulus length is 1024?

If I want to display the RSA key size... do I need to look at the x'04' section... and not rely on the title of the x'30' section?

Thank you

Colin
