SHA1 hash implementation for Particle Devices

API

SHA1Init

// PROTOTYPE
void SHA1Init(SHA1_CTX* context);

Initialize the context structure. Call this to initialize or reuse a SHA1_CTX structure.

SHA1Update

// PROTOTYPE
void SHA1Update(SHA1_CTX* context, const unsigned char* data, u_int32_t len);

Updates the hash with additional data. You can call this repeatedly with the same ctx to add more data to the hash if the data arrives in buffers.

SHA1Final

// PROTOTYPE
void SHA1Final(unsigned char digest[20], SHA1_CTX* context);

Finalizes the hash calculation and stores the SHA1 digest in digest. The digest variable must point to a buffer of 20 bytes to hold the hash. It's always 20 bytes (160 bits) for SHA1, other SHA hash algorithms have longer digests.

SHA1_CTX

typedef struct {
u_int32_t state[5];
u_int32_t count[2];
unsigned char buffer[64];
} SHA1_CTX;

This structure (72 bytes) stores the state of the SHA1 has. Initialize it with SHA1Init.
