1. Introduction

This document has various test cases for XML Encryption 1.1 [XMLENC-CORE1]. All the test files are available in this directory: files.
The test cases are organized as follows:

PlainTextThere is only one plaintext file plaintext.xml. All the encrypted files are encrypted versions of this plain text file.
Private Keys and CertificatesThe private keys and corresponding certificates are stored in files ending with ".p12". These are PKCS12 files with password passwd.
- RSA-2048_SHA256WithRSA.p12: Self signed RSA-2048 key.
- RSA-3072_SHA256WithRSA.p12: Self signed RSA-3072 key.
- RSA-4096_SHA256WithRSA.p12: Self signed RSA-4096 key.
- EC-P256_SHA256WithECDSA.p12: Self signed EC-P256 key.
- EC-P256_SHA384WithECDSA.p12: Self signed EC-P384 key.
- EC-P256_SHA521WithECDSA.p12: Self signed EC-P521 key.
- DSA-2048_SHA256WithDSA.p12: Self signed DSA-2048 key with |q|=256.
- DH-1024_SHA256WithDSA.p12: DH-1024 key signed with the above DSA key.
CipherTextAll the cipher text files are named starting with cipherText.

2. In-place encryption of XML

All the tests in this section take the plaintext.xml and encrypt it in-place, i.e. the root element of the plaintext.xml is replaced by <EncryptedData>. The details about the encryption key are embedded in the <KeyInfo>

2.1 Key wrapping

In these tests the

At first the content is encrypted by a random symmetric key .
The KeyInfo of the contents's EncryptedData has an EncryptedKey.
Then this symmetric key is wrapped by an public key.
The KeyInfo of this EncryptedKey has X509Data of the public key.

Encryption Parameters			CipherText	Remarks
Asymmetric Key	Content encryption algorithm	Key encryption algorithm	CipherText	Remarks
RSA-2048	aes128-gcm	rsa-oaep-mgf1p Digest:SHA256, MGF:SHA1 PSource: None	cipherText	All the examples in this table use the new AES-GCM algorithm.
RSA-3072	aes192-gcm	rsa-oaep-mgf1p Digest:SHA256, MGF:SHA1 PSource: None	cipherText	In this example the OAEP digest method is specified as SHA256. The MFG algorithm is SHA1.
RSA-3072	aes256-gcm	rsa-oaep Digest:SHA384, MGF:SHA1 PSource: None	cipherText	This example uses the new `#rsa-oaep` algorithm that takes in explicit `MGF` algorithm. The MGF has been specified as SHA1.
RSA-4096	aes256-gcm	rsa-oaep Digest:SHA512, MGF:SHA1 PSource: Specified 8 bytes	cipherText	This also uses `#rsa-oaep` but has a 8 byte PSource explicitly defined .

2.2 Key Agreement

In these tests the

At first the content is encrypted by a random symmetric key .
The KeyInfo of the content's EncryptedData has EncryptedKey.
Then this symmetric key is wrapped by a second symmetric key that is derived from the key agreement.
The KeyInfo of first symmetric key's EncryptedKey has AgreementMethod.
Key agreement is based on one sender's ephemeral key and receiver's static key.
The OriginatorKeyInfo of AgreementMethod has a temporary generated key indicated by KeyValue.
The RecipientKeyInfo of AgreementMethod has X509Data which is the receiver's public key.

Encryption Parameters					CipherText	Remarks
Asymmetric Key	Content encryption algorithm	Key Wrapping algorithm	Key Agreement algorithm	Key Derivation algorithm	CipherText	Remarks
EC-P256	aes128-gcm	kw-aes128	ECDH-ES	ConcatKDF	cipherText	In the first three examples the key wrapping algorithm size matches the symmetric algorithm key size. This is not required, the AES key wrapping algorithms can encrypt any data that is a multiple of 64 bits.
EC-P384	aes192-gcm	kw-aes192	ECDH-ES	ConcatKDF	cipherText
EC-P521	aes256-gcm	kw-aes256	ECDH-ES	ConcatKDF	cipherText
DH-1024	aes128-gcm	kw-aes128	dh-es	PBKDF2	cipherText	This example encrypts with a Diffie Hellman key with with the new algorithm `#dh-es` in which the key derivation function is explicitly specified.
EC-P256	aes128-gcm	kw-aes256	ECDH-ES	PBKDF2	cipherText	This example uses EC keys, but not the ConcatKDF key derivation function. Instead it uses the PBKDF2 key derivation. Also notice that the encryption algorithm and key wrapping algorithm have different key lengths - 128 and 256 respectively . The PBKDF2 parameters specifies a key length of 32 to match the wrapping algorithm key length.
