This file, by courtesy of Dr. Stephen Henson (drh@celocom.com), contains three Base64-encoded PKCS #8 EncryptedPrivateKeyInfo values, all making use of PBES2 and PBKDF2 defined in PKCS #5 v2.0. The first key is encrypted with des-cbc, the second with des-ede3-cbc and the third with rc2-cbc. The password in each case is "password" (without quotes). Once decrypted, they should all yield the same private RSA key.
