A Clojure library for accessing Amazon S3, based on the official AWS Java SDK.

Although there are a few S3 clients for Clojure around, this library aims to provide a more complete implementation, with metadata, streams and protocols for uploading different types of data.

Currently the library supports functions to create and delete buckets, and to list, get, and put objects and their metadata.

It doesn't support ACLs yet, but will do in a future release.


No release for this fork yet. Clone it or forget it.



(require '[aws.sdk.s3 :as s3])

(def cred {:access-key "...", 
       :secret-key "..."})

(s3/create-bucket cred "my-bucket")

(s3/put-object cred "my-bucket" "some-key" "some-value")

(println (slurp (:content (s3/get-object cred "my-bucket" "some-key"))))

Multipart upload without client-side encryption

(require '[aws.sdk.s3 :as s3])

(def cred {:access-key "...", 
           :secret-key "..."})

(def tm (s3/s3-transfer-manager (s3/s3-client cred))) 

; no client side encryption, no server-side encryption
(s3/upload-file tm "my-bucket" "some-key" "/path/to/file")

; no client side encryption, AES-256 server-side encryption
(s3/upload-file-sse tm "my-bucket" "some-key" "/path/to/file")

Multipart upload with RSA client-side encryption

You can create your keystore anywhere, a hidden folder in your home dir is a good starting place. The following will both create a keystore and add an asymetric RSA pair to it:

keytool -genkey -keyalg RSA 
        -dname "cn=John Doe, ou=IT, o=Acme, c=FR" 
        -alias my-alias -keystore /path/to/keystore 
        -storepass my-ks-password -validity 365

Then simply add the keystore and key info to the cred map.

(require '[aws.sdk.s3 :as s3])

(def cred {:access-key "...",
           :secret-key "...",
           :ks-path    "/path/to/keystore"
           :ks-pwd     "my-ks-password"
           :key-alias  "my-alias"
           :key-pwd    "my-key-password" })

(def tm (s3/s3-transfer-manager (s3/s3-encryption-client cred)))

; RSA client side encryption, no SSE
(s3/upload-file tm "my-bucket" "some-key" "/path/to/file")

; RSA client side encryption + AES-256 server-side encryption
(s3/upload-file-sse tm "my-bucket" "some-key" "/path/to/file")
