Function Documentation

◆ pbkdf1()

error_t pbkdf1	(	const HashAlgo *	hash,
		const uint8_t *	p,
		size_t	pLen,
		const uint8_t *	s,
		size_t	sLen,
		uint_t	c,
		uint8_t *	dk,
		size_t	dkLen
	)

PBKDF1 key derivation function.

PBKDF1 applies a hash function, which shall be MD2, MD5 or SHA-1, to derive keys. The length of the derived key is bounded by the length of the hash function output, which is 16 octets for MD2 and MD5 and 20 octets for SHA-1

Parameters

[in]	hash	Underlying hash function (MD2, MD5 or SHA-1)
[in]	p	Password, an octet string
[in]	pLen	Length in octets of password
[in]	s	Salt, an octet string
[in]	sLen	Length in octets of salt
[in]	c	Iteration count
[out]	dk	Derived key
[in]	dkLen	Intended length in octets of the derived key

Returns: Error code

◆ pbkdf2()

error_t pbkdf2	(	const HashAlgo *	hash,
		const uint8_t *	p,
		size_t	pLen,
		const uint8_t *	s,
		size_t	sLen,
		uint_t	c,
		uint8_t *	dk,
		size_t	dkLen
	)

PBKDF2 key derivation function.

PBKDF2 applies a pseudorandom function to derive keys. The length of the derived key is essentially unbounded

Parameters

[in]	hash	Hash algorithm used by the underlying PRF
[in]	p	Password, an octet string
[in]	pLen	Length in octets of password
[in]	s	Salt, an octet string
[in]	sLen	Length in octets of salt
[in]	c	Iteration count
[out]	dk	Derived key
[in]	dkLen	Intended length in octets of the derived key

Returns: Error code
