API​

noxtls_base64_encode​

int noxtls_base64_encode(uint8_t * input, uint32_t len, char * output);

Encodes data in Base64

Parameters:

  • input — is the input data
  • len — is the length of the input data
  • output — is a pointer to the buffer where Base64 data will be placed

Returns: number of bytes encoded, negative error otherwise

noxtls_base64_decode​

int noxtls_base64_decode(char * input, uint32_t len, uint8_t * output);

Decodes Base64 data

Parameters:

  • input — is the Base64 data
  • len — is the length of the input data
  • output — is a pointer to the buffer for the decoded data

Returns: number of bytes decoded, negative error otherwise

noxtls_base64_decode_char​

uint8_t noxtls_base64_decode_char(char c);

Decodes Base64 character to value

Parameters:

  • base64 — Character to decode

Returns: value decoded
