If you have DSA public key in file dsa-pub-key.pem then
to convert this to DER form use:
$ head -1 dsa-pub-key.pem
-----BEGIN PUBLIC KEY-----
$ openssl dsa -in dsa-pub-key.pem -out dsa-pub-key.der \
-outform der -pubin
read DSA key
writing DSA key
and to check:
$ openssl dsa -in dsa-pub-key.der -inform der -pubin -text -noout
read DSA key
pub:
56:59:95:61:9f:6a:bc:1c:21:a3:3e:d5:a0:1e:b9:
3a:93:9e:f6:4b:12:56:97:04:cd:2c:e7:b7:ac:5a:
....
$ openssl asn1parse -in dsa-pub-key.der -inform der
0:d=0 hl=4 l= 438 cons: SEQUENCE
4:d=1 hl=4 l= 299 cons: SEQUENCE
8:d=2 hl=2 l= 7 prim: OBJECT :dsaEncryption
17:d=2 hl=4 l= 286 cons: SEQUENCE
....
