Name:rypted_init - initialize an encrypted key* For a new key, use a random number for both the iv and data* itself. For an old key, decrypt the hex encoded data.
Proto:static int encrypted_init(struct encrypted_key_payload *epayload, const char *key_desc, const char *format, const char *master_desc, const char *datalen, const char *hex_encoded_iv)
Type:int
Parameter:
Type | Parameter | Name |
---|---|---|
struct encrypted_key_payload * | epayload | |
const char * | key_desc | |
const char * | format | |
const char * | master_desc | |
const char * | datalen | |
const char * | hex_encoded_iv |
763 | ret = 0 |
765 | If format && Not strcmp(format, key_format_ecryptfs) Then |
766 | ret = valid_ecryptfs_desc - verify the description of a new/loaded encrypted key* The description of a encrypted key with format 'ecryptfs' must contain* exactly 16 hexadecimal characters. |
770 | ecryptfs_fill_auth_tok((structecryptfs_auth_tok * ) payload data + datablob + hmac , key_desc) |
774 | __ekey_init(epayload, format, master_desc, datalen) |
775 | If Not hex_encoded_iv Then |
776 | get_random_bytes( datablob: iv , ivsize) |
780 | Else ret = encrypted_key_decrypt(epayload, format, hex_encoded_iv) |
782 | Return ret |
