DBK and LTK structure

Not sure about terminology, but it seems that what is stored in dm_docbase_config.i_crypto_key is a DBK, and what is stored in dm_docbase_config.i_ticket_crypto_key is a LTK:

[dmadmin@docu72dev01 bin]$ strings -a documentum | grep _KEY_CLASS
DM_DBK_KEY_CLASS
DM_LTK_KEY_CLASS
DM_FSK_KEY_CLASS
DM_PPK_KEY_CLASS
...

3DES:

AES:

The next challenges are:

  • Install TCS option and understand storage key structure
  • Create offline tool generating login tickets

AEK and DBK parsers are already done: https://github.com/andreybpanfilov/prodctm/tree/master/prodctm-util/src/main/java/pro/documentum/util/crypto
