So, right now I am using this code:
(let [username (get-in @um/interactions [:omniture-api-
credentials :username])
secret (get-in @um/interactions [:omniture-api-credentials :shared-
secret])
nonce (DigestUtils/md5Hex (str (math/round (* (rand 1 ) 1000000))))
nonce-encoded-base64 (Base64/encodeBase64 (.getBytes nonce))
date-formatter (new SimpleDateFormat "yyyy-MM-dd'T'HH:mm:ss")
formatter gmt-timezone)
created (.format date-formatter (new Date))
digest-as-string (apply str nonce created secret)
digest (.digest (java.security.MessageDigest/getInstance "sha1")
(.getBytes digest-as-string))
digest-base64 (Base64/encodeBase64 digest)
header (apply str " UsernameToken Username=\"" username "\"
PasswordDigest=\"" digest "\" Nonce=\"" nonce-encoded-base64 "\"
Created=\"" created "\"")]
header)
but when I print the header to the terminal, I still see values that
should be base64 but are not:
PasswordDigest="[B@3652831e" Nonce="[B@631e426e" Created="2\
013-03-04T13:26:21"
The classes I'm using are, I think, fairly standard:
(java.security MessageDigest)
(org.apache.commons.codec.binary Base64)
(org.apache.commons.codec.digest DigestUtils)
What am I doing wrong?
