Hi Vladimir,
$ openssl asn1parse <thekey
0:d=0 hl=4 l= 631 cons: SEQUENCE
4:d=1 hl=2 l= 1 prim: INTEGER :00
7:d=1 hl=2 l= 13 cons: SEQUENCE
9:d=2 hl=2 l= 9 prim: OBJECT :rsaEncryption
20:d=2 hl=2 l= 0 prim: NULL
22:d=1 hl=4 l= 609 prim: OCTET STRING [HEX DUMP]:3082025D0......
The real key starts at offset 26.
Use the following command to extract it:
$ openssl base64 -d < thekey | dd bs=1 skip=26 | openssl rsa -inform DER -text
But I've never seen this format before.
You don't want to use the key anymore, right ?
Cheers
Christian
