config DROPBEAR_CURVE25519
	bool "Curve25519 support"
	default y
	help
		This enables the following key exchange algorithm:
		  curve25519-sha256@libssh.org

		Increases binary size by about 8 kB uncompressed (MIPS).

config DROPBEAR_ECC
	bool "Elliptic curve cryptography (ECC)"
	default n
	help
		Enables basic support for elliptic curve cryptography (ECC)
		in key exchange and public key authentication.

		Key exchange algorithms:
		  ecdh-sha2-nistp256

		Public key algorithms:
		  ecdsa-sha2-nistp256

		Increases binary size by about 24 kB (MIPS).

		If full ECC support is required, also select DROPBEAR_ECC_FULL.

config DROPBEAR_ECC_FULL
	bool "Elliptic curve cryptography (ECC), full support"
	default n
	depends on DROPBEAR_ECC
	help
		Enables full support for elliptic curve cryptography (ECC)
		in key exchange and public key authentication.

		Key exchange algorithms:
		  ecdh-sha2-nistp256 (*)
		  ecdh-sha2-nistp384
		  ecdh-sha2-nistp521

		Public key algorithms:
		  ecdsa-sha2-nistp256 (*)
		  ecdsa-sha2-nistp384
		  ecdsa-sha2-nistp521

		(*) - basic ECC support; provided by DROPBEAR_ECC.

		Increases binary size by about 4 kB (MIPS).

config DROPBEAR_ZLIB
	bool "Enable compression"
	default n
	help
		Enables compression using shared zlib library.

		Increases binary size by about 0.1 kB (MIPS) and requires additional 62 kB (MIPS)
		for a shared zlib library.

config DROPBEAR_UTMP
	bool "Utmp support"
	default n
	depends on BUSYBOX_CONFIG_FEATURE_UTMP
	help
		This enables dropbear utmp support, the file /var/run/utmp is used to
		track who is currently logged in.

config DROPBEAR_PUTUTLINE
	bool "Pututline support"
	default n
	depends on DROPBEAR_UTMP
	help
		Dropbear will use pututline() to write the utmp structure into the utmp file.
