dropbearconvert: keyimport.c: fix BER encoding of secp521r1 keys (#69)
keysizes >= 128 octets will be encoded with a 3 byte header
which must be accounted by the optional-header
Reproduce:
master:~/build/dropbear$ ./dropbearkey -t ecdsa -s 521 -f K
Generating 521 bit ecdsa key, this may take a while...
master:~/build/dropbear$ ./dropbearconvert d o K L
Key is a ecdsa-sha2-nistp521 key
Wrote key to 'L'
master:~/build/dropbear$ openssl ec < L
read EC key
unable to load Key
