2 depends on PACKAGE_dropbear
4 config DROPBEAR_CURVE25519
5 bool "Curve25519 support"
8 This enables the following key exchange algorithm:
9 curve25519-sha256@libssh.org
11 Increases binary size by about 8 kB uncompressed (MIPS).
14 bool "Elliptic curve cryptography (ECC)"
17 Enables basic support for elliptic curve cryptography (ECC)
18 in key exchange and public key authentication.
20 Key exchange algorithms:
23 Public key algorithms:
26 Increases binary size by about 24 kB (MIPS).
28 If full ECC support is required, also select DROPBEAR_ECC_FULL.
30 config DROPBEAR_ECC_FULL
31 bool "Elliptic curve cryptography (ECC), full support"
33 depends on DROPBEAR_ECC
35 Enables full support for elliptic curve cryptography (ECC)
36 in key exchange and public key authentication.
38 Key exchange algorithms:
39 ecdh-sha2-nistp256 (*)
43 Public key algorithms:
44 ecdsa-sha2-nistp256 (*)
48 (*) - basic ECC support; provided by DROPBEAR_ECC.
50 Increases binary size by about 4 kB (MIPS).
53 bool "Enable compression"
56 Enables compression using shared zlib library.
58 Increases binary size by about 0.1 kB (MIPS) and requires additional 62 kB (MIPS)
59 for a shared zlib library.
64 depends on BUSYBOX_CONFIG_FEATURE_UTMP
66 This enables dropbear utmp support, the file /var/run/utmp is used to
67 track who is currently logged in.
69 config DROPBEAR_PUTUTLINE
70 bool "Pututline support"
72 depends on DROPBEAR_UTMP
74 Dropbear will use pututline() to write the utmp structure into the utmp file.
