"AES-128-CBC", "AES-192-CBC" and "AES-256-CBC"
"AES-128-CBC-CTS", "AES-192-CBC-CTS" and "AES-256-CBC-CTS"
"AES-128-CFB", "AES-192-CFB", "AES-256-CFB", "AES-128-CFB1", "AES-192-CFB1", "AES-256-CFB1", "AES-128-CFB8", "AES-192-CFB8" and "AES-256-CFB8"
"AES-128-CTR", "AES-192-CTR" and "AES-256-CTR"
"AES-128-ECB", "AES-192-ECB" and "AES-256-ECB"
"AES-192-OFB", "AES-128-OFB" and "AES-256-OFB"
"AES-128-XTS" and "AES-256-XTS"
"AES-128-CCM", "AES-192-CCM" and "AES-256-CCM"
