| 0x00080000 | This writes an output u32 to cmdreply[2](created context handle). | |
| 0x00090040 | (u32 handle for a context) This is used for destroying a context created by command 0x00080000. | |
| 0x000A0082 | (u32 contexthandle, u32 size, ((Size<<4) | 10), inbufptr) Writes an output u32 to cmdreply[2]. This uses a context created by command 0x00080000. | |

| 0x000C0080 | (u32 contexthandle, u32 inval) This uses a context created by command 0x00080000. | |
| 0x000D0084 | (u32 size0, u32 size1, ((Size0<<4) | 10), inbufptr0, ((Size1<<4) | 10), inbufptr1) Writes an output u32 to cmdreply[2](created context handle). This is the same type of context created by command 0x000E0040. | |
| 0x000E0040 | (u8 inval) Writes an output u32 to cmdreply[2](created context handle). | |
| 0x000F0040 | (u32 handle for a context) This is used for destroying a context created by command 0x000E0040. | |

Going by strings in the SSL sysmodule it appears the sysmodule uses RSA BSAFE(like certain other 3DS software), this is also likely where the "ssl:C" name comes from(RSA BSAFE "SSL-C").
Similar to HTTPC, each SSL context is used with a dedicated service session which gets opened after creating that context. Following creating the context + opening the service session, SSLC:InitializeConnectionSession is used from that service session for that context. Afterwards, all commands which require a handle for this context are done with this dedicated service session.
