Description
SEED-ECB with PKCS padding, denoted CKM_SEED_ECB_PAD
, is a mechanism for single- and multiple-part encryption and decryption, key wrapping and key unwrapping, based on the KISA (Korean Information Security Agency) SEED specification, electronic code book mode and the block cipher padding method detailed in PKCS #7. It does not have a parameter.
The PKCS padding in this mechanism allows the length of the plaintext value to be recovered from the ciphertext value. Therefore, when unwrapping keys with this mechanism, no value should be specified for the CKA_VALUE_LEN
attribute.
In addition to being able to wrap and unwrap secret keys, this mechanism can wrap and unwrap RSA, Diffie-Hellman, X9.42 Diffie-Hellman, and DSA private keys. The entries in SEED-ECB with PKCS Padding: Key and Data Length for data length constraints when wrapping and unwrapping keys do not apply to wrapping and unwrapping private keys. Constraints on key types and the length of data are summarized in the following table.
